Whats crazy is a lot of women do this, or go through this. Must be some baby hormone thing, I dunno. Most girls do this at 20 too.
Start f***ing a bunch of dueds and drag some poor guy through it.
Good news, she will whore herself tired, and realize she loves you. Might take a year and couple of guys later but it will
happen. OH and shes going to give you a STD if your not super careful. If you do have sex with her again. Put on a condom, and watch her face. She will get soooo insulted so pissed. But stick to your guns! Tell her to shut the f*** up and lay down.
Personally I don't think she respects you.
You went to a bar to pick up some chick but couldn't.. thats the problem. I think if you got your game back, then you could easily get her back. You need to relearn whatever it was you once had. And thats how to go out and f*** girls.
That's what was attractive about you. You had an attitude, an air about you that comes with the fact you know you can go out and f*** a bunch of different girls. Its Attractive. Get that back!! She will see that and find you attractive again.
