I'm going to break up with my long distance girlfriend and get with my former friend's girl
Why do you want to end the long distance relationship?
I've always liked her, I once slept with her before and know she wants to be with me.
I don't think you are thinking this through enough. It's not good to get involved with someone your friend used to date. You should make sure this girl is worth it before you break up with someone that really cares about you.
Actually I'm having sex with her and breaking up with my long distance girlfriend.
I think that you should leave that girl alone though. It is not okay to get involved with the person that your friend used to date.
