I personally have a hangup about my ex-boyfriend from almost 15 years ago. I don't talk about him to anyone, but I still feel hate and love for him sometimes, and it's weird that I do that. People have a way of affecting you, good or bad, for a lifetime. If it's a case where she is just obsessed with it and can't get over it, then she would need to talk to someone other than putting all the pressure on you.

But, on the flip side, I understand the act of "carrying a torch" long after their gone.
