Just want to get some advice.

I Was out of Friday night in a club in Bristol and picked up this alt chick, she was about (9) but im happy with that anyway she was perfect!! we related on so many levels and had a lot in common. went back to mine banged for about 2 hours straight...then she just got up and left! I was a bit confused so I texted her on Sunday but nothing.... not to sure what happened there. and now she's like crack I just want to bang her again.

any tips on what I could have done differently ?

The wolf.

Maybe the sex was bad...

Maybe because she knew you thought she was perfect and the standard was too high.

My guess is you're a good looking guy without much experience at what a 9 is, or what "perfect" means (nothing). She might have had a husband or herpes. Maybe she simply wanted sex and she has other priorities, like a kid at home -- you might never know.

All you can do is ask why you want her so bad again. Isn't your life awesome enough?

Congratulations on the lay, although you might want to improve your ability to keep women around. That's something you can learn as a pua.
