No. You know the old saying, "If two people can remain friends after a relationship ended, then they were either never in love in the first place, or they still are." 
Never heard that one, but, yes, both the exes that I loved, and they loved me back, are still friends. One is my friend, four years later, and the other, is my friend, two months later. The friendship came before the relationship, and is the most important part of breaking up. I couldn't NOT be friends with my exes. There's only one I'm not friends with, of the four people I've dated, and that isn't because of the relationship ending...it's because he changed.
