Well first of all the emotional affair would have been it for me because I wouldn't get past it, but for some of the other stuff I don't think he's necessarily wrong.
speak to any of my family. He’s cut them out as they make him unhappy. He can’t see that this makes life very difficult for me and is annoyed that I question his right not to see them/socialise with them etc
I think this part is fine. If he doesn't want to speak to them he doesn't have to, and yes it makes things difficult for you, but pandering to relatives or inlaws you dislike is something a lot of people can only do for so long and then they've had enough.
So for the past year or so I’ve gone to all friends and family meet ups with the kids, but alone. But this just makes him more pissed off with me.
In what way? Does he criticise you for going? Is he starting arguments with you or are you starting them by not accepting his decision not to go and be around them?
Doesn’t like me talking about our relationship problems with anyone, not even my best friend of 30 years.

He’s also refused to see any of our friends who he thinks I’ve talked to about his behaviour as he thinks I’ve lied to them about his mindset and painted myself as a victim.
We all need someone to vent to, but I can also understand why someone wouldn't want to be around their partners friends if they thought the friends knew all their relationship issues. How does he know you talk to him about your relationship problems? My friends tell me theirs but I assume they don't tell their partners/husbands that they were discussing them with me.
This was part of the argument we were having this week. He stopped speaking to my sister nearly 2 years ago because of something she did. It wasn’t the nicest thing to do but I ended up in the middle of the argument, with her just shouting at me because he wouldn’t speak to her. He still is waiting for that to be resolved by her coming directly to him. When I pointed out that all that does is put me in the firing line, his response was that I should be defending him and his views. And until he receives her apology, he decided he’s got no need to speak to her ever again. So I have to keep making excuses at family get togethers as to why he isn’t there so that I don’t have to have his argument by proxy.
Why was she shouting at you that he wouldn't speak to her? Was she trying to speak to him? It sounds very odd tbh
Why did you start making excuses at family get togethers though? Why not just be honest? When people fall out with family they don't tend to go to get togethers, that's normal. The first time they asked you should have just shrugged and said "he refused to come after the argument" instead of making excuses.
