I have already written of this in other posts. My children have started to love the new man in their life. Im am being torn apart from jealousy. I do not show it, to them, him or their mother. I just want them to be happy, of course i am their father, and i have a fantastic close and meaningful relationship with them, yes, i know, i will always be their Dad. But i would be lying if i didnt say how much this is hurting me, some of his behaviour has been disgraceful, yet i have stayed silent and have never said a bad word. I am asking for some coping strategies here.
