Is this controlling/possessiveness?

My boyfriend threatened me to tell him the truth about something and if I didn’t he would pay to get my Instagram chat (which is deleted) with someone else. I’ve told him the truth if I’m honest from the start but now he wants to get into my account and download deleted chats which I think it’s not possible because you can't retrieve deleted chats. I told him that it’s toxic that there’s no need to threat when I’m explaining myself and the truth. I ain’t hiding anything anyways but it’s the invasion of privacy it’s weird for me cause on Thursday he went through my phone I’ve never had a partner do that I’m hoping for a peace of mind he doesn’t I wouldn’t do that. What do you guys think?
