Re: my ex girlfriend
What she is doing is having her cake and eating it!! She presumably knows that when you go to her house and she makes the first move, you're not going to say no because you clearly still like her.
She is a tease, is leading you on, and doesn't sound like a nice person.
I agree that you should get out of this asap. It is not a friendship, if she gets her own way all the time and has you wrapped around her little finger!
