you're the one allowing him to treat you like that, allowing him to keep you around. Grow up and get over it. Time to break up, move on and start acting like an adult instead of a kid in an obsessive relationship. You can blame him all you want, but you're the one sticking around letting it happen
I think you very well know what you should do. There is no reason you should waste anymore time with him, he doesnt respect you, move on and find a guy who loves you for who you are not who he wants you to be.
Ill be blunt, but you need to respect yourself... He tells you what you can and can't do, goes through your phone and tells you he can never marry you... What the fuck you doin still around him? That's disrecpectful as fuck to you and you can only blame yourself... So either respect yourself and find yourself a real parner, or keep being his object to control until he gets bored or finds something "better"...
