With my exDP, autonomy was everything to him. He firmly believed his DC should have complete autonomy. I think he sees his DC as an extension of himself. Especially his DS who is very like him.
This caused real problems for a number of reasons: what about when they wanted different things? One wants x but the other wants y. Then what? (usually his DS gets his own way and his DD has learnt her needs are less important).
His DD is also quite eager to please and generally happy to go with whatever. This angers exDP and he would get animated and demand she make her wishes known. He couldn’t seem to accept that she’s happy to go with the flow most of the time. He felt she just wasn’t speaking up and would get angry. But often when she did speak up, her horrible brother would oppose what she wanted or ridicule her. ExDP always criticises her for not being more like him and his DS. He even says to her “why can’t you be more like Simon??!” He thinks demanding what you want is normal and thinks his DC should do the same as him (unless they happen to disagree with him of course and then he will shout at them!).
His DS is now so accustomed to getting his own way, that he clashes with his mother on pretty much everything. He thinks he should dictate how her house is run and should have an equal say to his mother. If she doesn’t do what he wants then he emotionally blackmails and bullies her. ExDP encourages this (a) because he sees nothing wrong with having complete autonomy (in fact he seems to think children’s needs should trump adults’ every time) and (b) because he hates his ex with vitriolic fury and loves nothing more than to encourage discord in her household.
When his DD is happy to go along with whatever her mum wants, he shouts at her that she’s not being true to herself and should stand up to her mother and demand x and y. He doesn’t understand that having grown up around conflict, his DD’s presiding need is to avoid conflict because she hates it and finds it upsetting. But because he and his DS actively seek it out, he cannot understand that DD is different. He thinks she is weak so he shouts at her. It is awful. She often calls me in tears not knowing what to do. I have to step in and tell him to stop being an asshole.
I can’t imagine having to coparent with him. It caused such a conflict between him and his ex when they were together and continues to years later.
When we lived together and had a blended family it caused huge problems because our DC were treated so differently. His got to do whatever they wanted but he was also huge on discipline and expected all the DC to obey his every word. He would be furious if they questioned a directive or if he had to ask twice! My DC just thought he was a dickhead, but his DC seem genuinely fearful and will obey without question. He has a thing where if he has to repeat himself he shouts “SECOND TIME!!!” at the person. Including me! He would shout this at me if he had to repeat himself. (How dare he speak to another human like that!)
My DC do not expect to be consulted about everything. If I said “we’re going on holiday here” they would be grateful and think how lovely to be taken on holiday/don’t care where. His DC would have to be asked their opinion before we could book anything. Consequently when their mum would book a holiday to somewhere perfectly fine, they would complain and say they don’t want go/hadn’t been consulted. DS has refused to go on trips which she’s booked as he felt they didn’t align to his wishes!!!! Honestly, you couldn’t make it up!!
He has raised one child who is afraid to say boo to a goose and will likely put up with awful behaviour from men because she hates conflict so much. And another who expects to do/get what he wants and is used to emotional manipulation and bullying to ensure he gets it. It was like watching a slow car crash and I am so thankful we got away.
