Bad Oneitis With Freshmen Chick

I've literally talked to this with about like 10-12 people already lol. I feel whenever I talk about it the oneitis goes away. Not sure if this is a good thing to do or bad thing.. Thoughts? Anyways here I go.

Met this freshmen chick and talked to her for about 30 minutes. Got her number and we've been texting back and forth. I take her out on a date for about 2 hours and pull her back to my room. We smoke there and I was being a giant pussy and did not make out with her even though I knew I could get it (in hindsight, I remember us staring at each other for 5 seconds). Fuck me. This was saturday

I don't know why but I feel emotionally invested with her and I've been thinking about her a lot for the past few days. I haven't felt like this since high school. I think I fucked it up since on Sunday I called her to hang out like spontaneously but she said she had hw and shit and didnt feel good (sick) but she offered to go out Monday but at the same time she warned me that she might flake on Monday if she felt bad. I think it might be a legitimate excuse. So she flakes on Monday. 

I text her: Cool. Feel Better. And I text her again afterwards cuz I'm a needy faggot: "I almost got hit by boba. This couldve been avoided *cough cough*. <- this text was an inside joke since we got boba and we were joking about shooting boba at people. but I think I completely fucked up with this text. I thought the "cool. feel better" text was dickish and I wanted to smoothen it up...

She didnt respond. I think the vibe is off now but I'm going to text her again on Thursday. Thoughts on how to bring the vibe back? I was going to text her "I think we might have money problems" and when she responds then "i'm pregnant with your baby, it was proobably the honeydew melon boba..." (<- inside joke since I told her that it tasted nasty)

Anyways you can see how invested I am through this chode post. Its actually ridiculous. I know the solution is abudance but eh.

Haven't felt this way about a girl since high school. And I do have 2-3 weaker leads on the side. This was a good lesson to just fucking go for the close when you can and not think you will see her again.
