I wouldn't ever consider going back to my xh. I don't want to meet him for dinner or act like we are friends. We are divorced for a reason and are civil as we have a child together and of course I don't wish him harm.
I was told today that someone I had thought was a good friend (we fell out a few months ago as I realised she really wasn't) has gone back to her xh. He treated her terribly, he left her several times in the marriage, cheated on her, cut her short financially to make her accept a low financial settlement, didn't help with their child and cut contact as a punishment. She has a terrible relationship with her elder child who is not his and who always felt that she put the ex above her and whom he treated very badly. Anyway after the divorce he made a lot of money something she clearly resented and money was what she was looking for in another partner. She fell out with me and other friends and is now back with him and off on a luxury holiday after moving into his detached house. All I can feel is pity. Why would someone go back to a man who treated them so badly that they are divorced from just because there is money? I really feel like this is the only reason she is with him and others do to. Is it low self esteem? The inability to be happy in oneself? To me is like the proverbial dog returning to it's own vomit. Well good luck. From the outside looking in. ... It's not looking good.
