So I've been friends with this girl for a while and I just found out that she feels comfortable around me like she has never felt before. She has a b/f. She has made it pretty clear that she wants to be with me... but the problem is my ex (by the way she is still in love with me) is her best friend. And her b/f is one of my friends. I don't know what to do about this. Is there anybody out there that has been through this and can answer my question? What do I do?
