I keep coming back to this topic, but I decided to finally comment.
You don't need him... He sounds like a jerk honestly, if he can't trust you or believe in you, then he's loosing someone special, this sounds like a bad relationship. I agree witg what the others said, find yourself a guy who will love you, trust you, and believe in you. Someday your man will realise his mistake, and know he lost someone amazing.
