I really don't get why IndiReloaded and bcgirl are so angry at the OP. :|
OP, I think he never really cared about you, so you did the right thing breaking all contact with him and moving on. I don't know the reason why you still haven't broken up with your bf, but I kind of understand how it can be really difficult in certain situations. Just remember to take your time to get over this relationship after you do break up, before you start seriously dating somebody else. Even if the relationship is long-dead, it never really is until you break up officially. So yeah, take your time to be happy by yourself, and next time don't get involved with someone who is seeing somebody else : ).
