Peace, it is good that xmil as contacted you regards your kids, at the end of the day they are her grandchildren. I too know how you feel with all this crap, we have been at it for a long time, your sitch is similar to mine although I dont work with my ex, my ex doesnt have a mother she died some 17 years ago, but he as his old aunt who is his mothers sister, she is all he as left to run to , but when myself and aunt made amends I too hear in her conversations the deep hurt ex as caused and she too wishes he had never gone off and done what hes done, she is also saying she wishes he was back with me and hates his new wifey, it is a strange thing this mlc it doesnt just affect the mlcer and his spouse it affects many other people whether it be family or friends,and it is also strange how those family and friends can see that ex is not enjoying his new life, new love, new friends but he is in fact just self destructing and that is all it is, take care peace and hold your head high, I know this is hard and believe you me I am with you on every bit of your journey, xx
