My husband is hiding something, Advice please!

So yesterday my husband almost broke down the door and almost knocked pregnant me over to get his phone back from me.

Back Story:

While dating, i set the password for his phone and he would even let me read his messages and chat with his friends. After we got married (7 months now) he would lock the phone when i come near him, wouldnt let it out of his sight. I spoke to him about it and he said i’m making him uncomfortable with me “trying to invade his privacy”. I apologized and felt bad but he had access to my phone so why can’t I? It wasn’t a big deal while we were dating (for 4years).

His new work had him get a new phone so now he has two and i don’t even know the password to the other one, he sent it once after i told him to share but it was a sequence i didnt bother to learn.

Yesterday, i came out of the room he dropped the phone and as i got closer, he locked it and i was like you have a message, he said it was from his boss and I’m like won’t you reply? He was like not now, i picked the phone and jokingly ran to the room and thats when he almost knocked me over, hit the door on my hand and snatched the phone.

The fact that all he thought of was getting the phone back regardless of whether me or the baby get hurt or not broke my heart.

What is going on? I’m currently not speaking to him and told him to only come to me if he wants to reveal what he’s hiding.

PS: forgive my typos and i’ld appreciate advice. I can’t tell anyone close to us yet.
