Most Helpful Guy
it is very rare for two people to stay friends after a break-up. Its rare but it happens, and i am all for it. I think it is a special kind of friendship, one you dont get if you were friends in the beginning and then never dated.
Think of Jerry and Elaine on Seinfeld. All those adventures and good times wouldn't have happened if they didn't stay friends after they broke up. If you aren't right for someone, breaking up can be a good thing. Then, if you stay friends, you can be better friends because of it.
I say it is a healthy thing to stay as friends. You already know each other very well so when a problem comes up and you turn to each other, you'll be able to support your friend better than most.

I would have a talk to him and let him know that you and him breaking up isn't easy for you and that it's going to take some time before you guys can be friends. Then just take some time to get over him and meet some new prople and then maybe invite him for coffee or something.
He should understand. Its difficult going from an intimate relationship to friends. Especially since he was the one that broke it off with you.
