Yeh,but it doesnt need to be a relasionship for her to get emotionally commited.
I kicked it with this girl for a night, fucked her, then went to sleep, and my natural human instict was to hug her/have my arm over her.
She thought this was some connection we had cause we were lying there in passion. Couldnt get rid a the bitch.

So yeh, you played your cards right.
but damn, i wouldnt of left a bitch in my hosue without either me or one of my bros close by.
