I don't really care about PUA language and phrases that much, but one thing for sure is that you should have fucked her, end of story. You pussied out because your emotions told you to "treat her well" when all she wanted to do is fuck. It's not a surprise that she's not contacting you. As a matter of fact, it's the right thing to do.

Sex = higher investment from her side.

Hey guys, i think i need some advice.

I recently went out and met this girl i already knew briefly.
We were both drunk, but still in control and after a while we started to make out. At this point it seemed to me like she was into me alot. She asked me if we should drive home so fast i was really surprised, i agreed we went to my place.
But then she started to say like "im so drunk" a lot which i interpreted a bit in the direction of shes putting all the reason why this is happening on the alcohol which made me a bit insecure.
So at home we continued to make out in bed for a bit, but it was not very passionate. For the lack of passion i felt turned of and asked here if she wanted to sleep, she cuddled to me but nothin more and so i asked another time and she just didnt answer any more and we slept.
Im not sure what happened there, if i misiterpreted and she just wanted me to prove my confidence anf lack of fear of being rejected, or she genuinely regreted to come to my place.. well at least at this time I felt insecure and didnt want to force nor wanted to be rejected.

So man and i have to admit the next day she asked me to drive her home (shittest?) I did, which probably was a big mistake. Now a few days later i wrote her on fb and shes not responding. I know i probably fucked up a few things, im obviously not a pick up god and just lucky for being pretty handsome.
The thing is, i like this girl quite a bit and would be happy to meet her again.

You think theres still something to do? Otherwise well it would be at least nice to make my mistakes more obvious so i can learn from them.
