Can you be friends with your exBPD?

[Valentine09]

I've never been able to separate my romantic feelings for her (no matter how despicable she is)  to the point where I can only see her as a friend.  The only way to do this is if I never see her face.  Then, it's like being friends with a ghost, or one of those foreign pen-pals they'd have you write to in school.  That's not what I consider a friend, it's what I'd consider an acquaintance.  If I wanted that kind of relationship I'd get on chatroulette.com  and talk with strangers all night, and probably have a more satisfying conversation.
