Donna, being friends with the ex is difficult. I know people who, like yourself, try it and get taken advantage of. It often ends negatively. It'a a tough line because you want to be mature and show the children how adults SHOULD handle difficult times but again, like a marriage, it takes two people with similar goals in mind. My STBX and myself get along pretty well and both of us have similar mind sets as to what we want from it. That said, I don't call her "just to chat" or anything like that. We do spend "family" occassions together and we both know if one of us needs something the other will help out. We're pretty lucky that way, for many it doesn't work out. Btw, just because your ex isn't showing any pain doesn't mean there isn't any. People act out their pain and guilt etc in different ways and if they don't in the long run suffer big time. You feel your pain and heal, that's the way to go! Feel better
