Hi Tiny Elephant. To me, those are very bad signs and red flags. Uncontrolled possessiveness and control are toxic and abusive things. Everyone needs some alone time and time with other people to be healthy. I experienced something similar recently with enmeshment and someone who was jealous, controlling and possessive. It was purely toxic. You don't deserve to be treated like that and I feel that it will consume you at some point. It seems like, in these situations, these types of people do not change unless something drastic happens. He may feel he is entirely justified in how he behaves and so he doesn't need to change at all.

I wish you the best and I do hope you are able to find peace.
