He suffers from jealous, insecure, possessive, controlling man disease.
A disease for which there appears to no cure.
A disease that causes their partner significantly more suffering, stress, lower quality of life, restricted life etc.
You started a thread about him going on about you daring to wear a thong under trousers to get a bit of air around your bum etc in hot weather.
Now you've added, among other things, that he stood you from going out socially alone.
He's a nut. He's not right in the head.
And I'm sorry, but I e never known men like this to change.
I ended a relationship with one of the after a year or so of that type of shit. Except I didn't ever accept him ruining my social life and stopping me from socialising separately so it was arguments and "we're finished" every month or two ...or however often I dared to go out socially or dared to accompany a friend on a break so she didn't have to play gooseberry with her brother & his gf of the time.
You are in an extremely controlling relationship. That is abuse. It's also illegal now - coercive control.
