I think it will get worse if you let it. Do you know anything about his past relationships? Maybe he was cheated on and is now scared any and all women will cheat so he keeps you on a tight leash. Or maybe his dad was the same way or maybe it's another reason in a sea of reasons why he acts the way he does.
Whatever the reason, he needs counseling to learn how to act in a healthy relationship.
FYI if I was in your position I wouldn't put up with this one bit. Ice said it before and I'll say it again, an emotionally healthy person doesn't put up with that kind of crazy. He may not be crazy in all aspects of life but controlling an adult in this fashion is crazy to do and crazy to put up with.
