Hello again, wrote long post but it dissapeared.
To summarise, it's not just he'll complain, he'll do something to show he can control some other way.
e.g after he started argument where I just said no to an unreasonable request (paying one of his bills), as little as possible words, he started tiride of abuse, about how lazy I am, only work part time, etc etc. he wouldn't leave inside hallway, when I finally got him to leave he kicked the door. (First time he had ever done anything like that, presents himself to the world as very respectable and calm.) Children were upstairs upset and comforting each other. I then told him he must collect kids from doorstep, in future, not come in.
So he waited a few weeks then started another argument, would have meant I had to either give in or say something. Usually nowadays I have learned to ignore. I started shoutingmay have raised my voice a little, that is what he wanted. Then he told children he won't come to the door any more as mum always argues. He texts them (not me) when he is a little way down the road and I watch to check they get to him ok, he texts to tell me not to spy on him.
Another time as i said upthread, and I think this is the worst thing recently and means he'll do things he wouldn't previously relating to dcs, he ignored my "no", tried to just take dc. He told another DC to fetch something he needed for DC he wanted to take, overiding me. Not taking no for an answer.
So what will he do next time I say no to something (this holiday)? Take them in camper van anyway, by asking to have them day before and not bringing them back? Come in car for afternoon outing then say here's a surprise children, we are going to drive to the camper van and go anyway? Text them to say meet me down the road and don't listen to/or even don't tell mum? Something else entirely?
This has always been the problem, what will he do next?
Oops turned out long post again.
