Buyer's remorse??

After going on a day 3 with a girl (HBballet) and bringing her back to my place and end up fucking her, I randomly meet her out one night at a bar. She's there with a group of her friends and I with a girl who I'm trying to hook up with and other acquantances. Anyways, she introduces me to her group and one of the girls is a cutie, my type. Don't think much about it as I'm trying to hook up with this other chick.

Fast forward week later, our scheds are pretty busy so we can't meet up but I'm out doing some night streetgame and the first girl I happen to stop is her friend. I hadn't a clue when this happened except when this girl actually brought up she was the best friend of the girl I hooked up with. She goes " do you do this often bla bla bla". Night goes on and I decide to pre-empt the situation by texting HBballet, as I picked up on this vibe that her friend was not having it.

Me: Funniet thing I bumped into your friend haha Thought I'd fuck around with by hitting on her ;p

(No response)

Next day

(Send pic of 3 burgers)

Me: Hey boo how's your day going. I'm about to die from a heart attack

(3 days later)

Talked with girl roomie, to kinda hash out where this girl might be at.

Me: Hey you. I apologize if what I did upset you. That wasn't my intent at all. and I get that I may come off as a sleazeball. Telling you I met some really cool guys probably won't help either, but I did! Sorry name

Her: Hey! It's all good. I'm not upset about you hitting on my friend, you're entitled to hitting on any one you feel lile. I just thought our 2nd date was a bit too much and I'm not interested in taking it further. Glad to hear you met some cool ppl. Have fun at NXNE!

Now I get we're not supposed to be apologetic about our actions.

I wanna know how you guys might have handled this situation differently, (kinda reminded me of Manwhore's response to the naughty nurse after her buyer's remorse)
