Bf using my phone

My bf has been using my phone a lot recently. I’ll leave it in a room and forget about it, I’ll go looking for it later and he’ll have posted random pictures to my Snapchat story, be looking something up online, or will be putting it down when I walk into the room. I’ve never addressed it other than “oh there’s my phone, I forgot where I put it again haha”.

We know each other’s phone passwords, they’re actually the same and have been our whole relationship. The thing is, I don’t like when he uses my phone anymore without asking. I never use his phone without asking. If he’s not in the room, obviously I don’t touch it or go through it.

During a rough part of our relationship like a year ago, he invaded my privacy in a big way. He’d gone through my phone while I was sleeping. He went through every text convo, Snapchat convo that was saved, etc. In the morning he was pissed bc id been texting someone and told them literally everything that happened in our relationship. I felt like the bad guy and wanted to fix things but didn’t know how. They’d been through something similar so that’s why we’d been messaging. My bf was pissed bc they were a guy and was convinced they were into me and I was “cheating” somehow. I did suspect the guy had a crush on me, but he was also very aware I was 100% set on fixing things with my bf and he was also still hung up on his ex. Plus at that point I was desperate to talk to someone who actually understood what it felt like to feel like everything in the relationship was their fault.

For weeks after he continued to go through my phone, laptop, internet search history, etc. and interrogated me after. Almost every night I was in tears bc he was constantly accusing me of cheating when I wasnt. I’d look up something innocent, and he’d be trying to flip it. Finally I told him he needed to stop. I’d been run through the mud enough - maybe I shouldn’t have texted a guy and told him details of our relationship, but I was at my lowest point and had no where else to turn and needed help from someone who understood. I said if he kept acting like this, not trusting me, then I would leave bc this is no sort of relationship. I’d know it was my fault, but I didn’t deserve that kind of treatment and neither of us were happy in a trustless relationship.

We actually made it out of that dark spot, idk how, and things have gotten massively better. Fast forward a year later, we have a new house together, a puppy and a kitten, and I had gotten pregnant. I lost the pregnancy after two months and took the loss pretty hard. Obviously we’re in a very different place than we were.

However even now, whenever I see him on my phone I feel my anxiety kick into over drive. Obviously I’m not hiding anything on my phone, but I know he’s probably gone through everything. If he asked to use my phone for something specific, I wouldn’t care. But I feel like I have no privacy when he goes through my phone when I’m not there.

Idk what to do anymore

UPDATE:

Also, I really don’t think he’s going through my entire phone anymore. It’s mostly just I’ll find my phone and find out he posted a picture to my Snapchat story, or I’ll see him on it, and I flash back to a year ago when he was going through everything. I feel like I don’t have privacy bc the last time I didn’t have any, and when I’m not in the room idk what he’s looking at.
