I've always been the stronger character whereas during our 23 year marriage, he was an introvert, but none the less, behaved like an adult.
We've now been divorced for 5 years (he was having an affair with OW who is 18 years younger than him and not from the same culture or country) and sadly still have to have some sort of contact due to on going legal stuff and joint children.
What I've noticed is that the ex (aged 53) has regressed into being a complete child over the last few years which I find bizarre behaviour. He seems to play childish games with our lawyers, replies to emails in the most petulant way (think "my dad's bigger than your dad" scenario), flies off the handle over minor things that would not even be noticed by a normal adult, rings up our adult kids to say he has no money and he's sad (hardly a role model and he earns ££££!), hides things from our kids and his family (new baby and secret "visa' marriage), threatens me with the police ALL the time and how I may lose my job if I say one word that he feels is unjust to him!
Personally, I think he is unhappy. He got the OW pregnant three months into their affair and he's now stuck in a situation I don't think he feels happy with.
Any thoughts on how to handle this behaviour or why the regression?
