Have you considered therapy for yourself? There must be a reason for you wanting a relationship with someone you can never be fully together with. Well that a separate issue

I am not sure why you need to disclose everything to him? People deserve having private info. There is no rule you must be open book with him. Why?

His behavior is irrational and you can’t pissibky fix him. We can’t control what other people do but you can cintril what you do. So I’d focus on myself
