Thank you so much ladies for your answers. There is some seriously good advice here. I will need to do a deep self analysis over Christmas and work out if it's possible - how it would be possible and if i can live with sharing the childcare with him given that I think he would struggle on his own. Getting into a fight regarding custody would be a disaster and would completely alienate his family as well and I don't have family around here.
@Boulshired I hear you, I do wonder if the damage is going to be so long lasting and that I will be responsible and colluding because I did not have enough strength to leave
@cheeseburger100 that is exactly my main worry, if we were to split he would most definitely try and get 50% and he will be unsupervised on his own. And whilst he has so many good things as a parent, his lack of understanding is very damaging.
@Breakingplaid, I am so sorry to hear what is going on, it's not easy for you. I also worry my house will have continuous scenes of devastation if I keep being here during my son's teenage years (he is 8 now and the problems are getting worse)
@madcatladyforever , yes I am seriously starting to think this is not for me any longer, but having the courage is another thing, you words are very powerful
@mummax3 sounds like you have been able to ride it and things have calmed down for you, that is amazing well done.
@Waveysnail thanks really good advice. We did the 'positive parenting course' in theory he agrees on all the principles but in practice it's another story, ee can't see the consequences of his behaviour and what happens is always someone's else's fault :-(
