university colleague, interested or not - your suggestions

This will be a long read, I know, I try to keep it as short as possible, but I want you to know the background, so you can give proper advices. Thank you in advance!

Background:

My position in university: I am the students' delegate which means, I am organising parties and stuff, literally nothing happens without me.

First meet outside university: The first month I really didn't notice her. I mean I noticed her presence and her attractiveness, but not more. Then there was the first university party and she was there too. I was busy building connections with my mostly male colleagues, so I didn't talk to her. But as we were moving to the dance floor, she suddenly was touching my back and tracing her nails over it, to make me shiver. Since then she was in my concious.

The real open: The next students party arrived appr. 3 weeks later, she didn't attend. So I opened her over facebook with "Where've you been yesterday?". Since then I was texting with her, two weeks later I got her phone number out of the blue.

Problem #1: A female friend of mine (who is seems to be one of the few women who know what women really desire, mostly is accurate like the pick up I was taught) told me that I was texting way too much with her. Didn't really follow that advice.

The big incident: Until this day there have been appr. 3 meet ups with just talking, no explicit game, but already teasing from her and touchy responses on my teasing (punches on the shoulder, light pushing). It was a going out because of a colleague's birthday. We went into a pub and I missed the time I should have stopped drinking. Drunk I began to become too touchy and negged her (both too much, as I know now).  Also took her cigarettes and phone, playfully. To that she responded in touchy "punishments" like scratching my neg and arms. That was not the biggest problem, as one of her best friends (also a colleague of mine) stated later. I negged her nose, her biggest insecurity, which hit her hard. Not bad enough, the next day I fucked really up by sending her needy and apologetic messages like "Tell me if you are still mad because of yesterday" and so on. To which she didn't respond, just to every message which didn't mention the incident. As I know now, since her best friend told me later too, she "forgot" this incident, because she (in his opinion) likes me too much, to be mad about it. So, I didn't mention it again.

The texting fuck up: We got back to texting as before the incident, she even blew up my phone with spaming me over whatsapp with variations of my nickname. 50 messages in total, just in the middle of the night. Followed up by a picture of her broken car.

On the next day I sent the following:

Me: Is this your car?

Me (minutes later, she was shown online on whatsapp): Are you injured?

Me (minutes later, she was shown online on whatsapp again): You can tell me if something's wrong with your family again...

Me (minutes later, she was shown online on whatsapp again): (some angry, reactive text I've forgotten because I did delete these messages from my phone)

Three days afterwards we had to meet in university, because it was exam day. I was nervous as hell, never feels good if you don't know if sombody's angry at you. First it was really cold, she didn't talk to me. But suddenly after the exam she came to me and asked how I did and we chatted shortly, but not as friendly as before.

The ignore week(s): This was a big wake up call and I didn't text her for a week and a half, I guess. That's when she started texting me, with weak excuses (like asking questions about university or my learning progress etc., something she could ask everyone else, but not me (nothing of these excuses did have anything to do with my task as students' delegate), I thought after the big incident and the text fuck up). I didn't text back or I did, short and in half an hour/an hour/several hours. On the end of the week, we hadn't texted or in person contact for three or five days, she texted me:

Her: tomorrow

Her: Going out?

Me (fifteen minutes later): Who else will come? (didn't want to seem too excited or that I just jump because she texts me)

Her: (lists some colleagues, all good friends of her)

Me: Ok, tell me the time for meet up tomorrow!

as she did

The first meet up in a pub after the incident: She wanted to flake:

Her: Who's there in the pub already?

Me: (listing up the colleagues)

Her: Yeeah I am going to get ready slowly and then I'll see. I am not feeling 100% well.

Me (two minutes later): No, you will come. You can leave earlier like 2 am, if you feel not that well.

Her: I've got a really bad stomachache :(

Me: That will go by, I've got a headache. Come on, hopp!

Her: Yeah, I will come. I am getting ready and will look for some medicine.

Me: Good girl

Her: Always

She did arrive late, but she did arrive. She didn't end up next to me, but later I arranged with a colleague, that he and I would switch, because "You always shut me out from the most interesting conversations". So I ended up next to her and we talked about movies etc. Just what came to my head. Getting rapport with her was my main goal, but I never forgot to keep eye contact etc.

The next meet up attempt (students' party, no one on one) she excused herself because she was too tired and had to leave for another city early the next morning. So legit and honest excuse.

Some texts:

Me: Are you already back? Are you up to laugh about desperate women on Friday? :D (Friday was Valentine's Day)

Her: Yees :) Yeeees I'd love to :DD

Me: Then it's fixed. We are going out. Let's see who comes with us^^

Her: yeeeessss

Three days later:

Me: I am too nice for this world :D

Her (half an hour later): Why

Me (1,5 hours later): I am helping our colleagues out. During MY holidays.

Her: Nice of you

Me (fiteen minutes later): (exam result)

Her (fifteen minutes later): (y)

Me (half an hour later): You? You don't seem very talkative today :P

(did stress me a bit, because she was online several times)

Her (ten hours later): Wait, I am looking it up. Had a terrible headache and throw up several times :( (her exam results)

Me: Are you ill? :O Nice :D

Her: No fever   I don't know :( It is getting better now

Me: Go sleep and rest. I now have too, because I have to work tomorrow

Her: Nice nice! Yeees I will too soon ;)

The next day was some chitchat initiated by her. Like:

Her: Were shall I go on summer vacation?

Me: I got told that it's very nice in my bed :D :P

Her: Doesn't seem good for partying :D

Me: Oh, you've got no idea. Seems like you have to come along some time :D

Her: :D hahaha you would like that wouldn't you :D

The meet up on Friday: While I was on the way to the pub, she texted me if I was already there. After half an hour she arrived too, we were alone. She immediately started talking, I didn't need to say much. Later some colleagues arrived and three of her friends. I thought I've lost her for the whole evening and started talking to my colleagues, suddenly she reengages me by tapping me on the shoulder and asking me to contribute to their conversation.

I really did well I think, her friends seemed to like me, so I came back to her, talking to her about somethings like that she would leave the next day for a journey and that she would have to send me some photos. Suddenly her friends started to take photos, which she didn't really like. So she throw herself onto me and hid her face on my shoulder, although her friend since 5 years would have been on the otherside of her. Then she talked about how they four went to a swimming hall and how I should go with them the next time (going one month or so back, she had also talked about this swimming hall and said that I would have to go there. She didn't say with her, like she did on this day). As she stood up to go to the toilette, on of her friends sat next to me.

As she came back, he sat between us. I again started talking to my collagues as she reengaged me into the conversation and some time later, her friend stood up to go to the bathroom and she immediately sit back next to me. Then I asked her, when she wanted to leave and I managed to delay it by half an hour, so we could go together, as I said to her. As we left, we both went to the bathroom. As I was finished I went outside and waited for her. Ten minutes later she came out and said that she has been waiting inside for me. We went on and suddenly she parted ways and said a short good bye.

The next day I texted her:

Me: Hey you, have fun in [destination], try to not make your Mum broke :DD

Her: I'll try :D Thanks

On the day after that:

Her: (sends three pictures, one out of the plane, two from her hotel room)

Me (three hours later): Awww, I want to :P

Her (three hours later): :D

Her (ten minutes later): So the nice weather here :D

I didn't text back or texted her the whole journey. Today she said she would be back, so I texted her on facebook (because she was shown being online, which wasn't true as I saw then):

Me: Are you back already from [destination]? Do I have to be scared in the dark now again? :D :P

Since then she hasn't responded. She is online on whatsapp very often today and already was on facebook, but didn't mark my message as "seen".

Text comparison:

before being aware of my texting habits (around November):

Me: I am going into the shower now, you can come along if you want :P

Her: ugh beh, no thanks

now (around January):

Me: I have to take a shower now, your chance for stalking me and seeing me naked :P

Her: :D hahaha Let me have my fun :P

Me: I know I am awesome, but please come the fuck down :D

Her: :DD hahaha

What's your overall impression? Any suggestions?
