Everyone here is right. Run. Run fast.

Nothing in his behavior is good, right or normal. He is a controlling, demanding and will end up being a smothering bf if not soemthing much worse.

I would not ask a woman even my gf for her password on her phone unless there ws some reason to do so at taht point, and if there were a reason to, I'd be questioning the relationship already. A relationship is going to have problems no matter what, but it needs to start out with a foundation of trust to be able to endure the normal issues. Without that in the beginning the only way from that is a downward spiral. Trust me.
