My ex is a wanker and I'm not sure how we ever managed to sustain a relationship (albeit a very toxic one) given that we have such different views on basically everything.
Ex can be very sexist, aggressive, controlling, he was a big covid denier which caused issues with contact during lockdown. He has a very short fuse with our ds 12 and his younger kids with his new wife. Hes just generally quite unpleasant and too pig headed to ever consider that any opinion or belief that differs from his own could have any value.
This is causing issues with my ds who thankfully is nothing like him. Ds is approaching his teenage years and has opinions of his own. If his dad doesn't agree he will simply shoot him down. Ds also is quite sensitive whereas ex is a big burly man's man. There often comments about him needing to toughen up and get a grip. I think ds is frightened of him and always keen to please him. He's usually on his best behaviour there and saves all the attitude and bad behaviour for me and my dh (which is annoying but also reassuring that he feels he can be his natural self with us).
Ds started senior school and has missed the bus home twice due to not knowing his way around. I picked him up. When his dad found out he really laid into him about being useless and taking responsibility. Then turns on me for being too soft and how I should have made him walk home (it's 5 miles away through fields and busy roads!) This is the sort of thing I've had to deal with since we split up when ds was a toddler.
For my own mental health I feel like I need to limit contact with him as I feel like even though we've been split up for 10 years, both remarried and both have new kids he's still able to trigger an anxiety response in me. He makes me feel bullied and intimidated even through messages.
But what about my ds? I hate to think he is experiencing the same. Despite his behaviour ds actually does love his dad and enjoys time with him (when he's being normal). But I can see them coming to blows in the next few years as ds grows and I can't bear to think of him feeling the anxiety and intimidation that Ive felt and still feel now. I know there may well come a time where ds chooses not to go there or becomes too busy with his own life (obviously this will be unacceptable and will all be my fault or ds fault, nothing to do with ex and his shit behaviour). But until that point, how do I make sure my son knows that his feelings and opinions are valid and that it's ok to make mistakes now and then, despite what his dad says.
