Had sex. Kissed her goodbye. Two hours later she says on facebook: Last night was so and so in the aspect if it was worth it. Anyways I don't want anything new as I've just moved to this apartment so I need to take it easy for a while.
Does that mean, I'll never have her as my gf? Would it be pathetic to ask her out after she has said that?
Well you fucked her so unless your endgame is a happy relationship I would just chill and see what happens. If you get wrapped up in emotional drama you are gonna have a bad time. She may come back for more and she may not but who care you already nailed her so why play emotional games.
>tells you last night was so and so
You blew it dude, move on. Don't chase her, it will only make her think you're creepy.
Stop talking to her and you have a small chance of her coming back.
