Has anyone gone through this what did you do ?

I went through my boyfriends phone because he was being weird about me holding it I found nudes saved of 3 girls on Snapchat and one convo with a girl that he was saying she hoped she had a good week then a good day one other time, I also found Instagram dms with cam girls flirting back and forth talking about being horny and one girl I went to school with he slid up on her stories and said damn. when I confronted him and asked for the whole truth at first he tried to deny and say I just woke up I was dreaming then when I named their names he said they are random girls off tinder and older they are in their early 30’s (we are turning 25) he has an older woman kink because of not having a mom figure he said and he said it’s strictly sexual and he just likes to play around and get adrenaline and excitement from it. He reassures that he is still attracted to me and he confessed when I wasn’t home for a week on vacation with my best friend for her bachelorette party he then said he re downloaded tinder to find these women and get their pictures on snap although some of the snaps and dms go back to 2019 when our relationship started it wasn’t everyday but there were some recent from February and may, he also had a girls very explicit pictures saved in my eyes only on Snapchat he swore he never met up with anyone and wouldn’t cross that line and deleted and blocked everything and he promised to never do it again and he’d appreciate me more he said he loves me and he was a idiot who had terrible examples of parents when relationships and didn’t know how to have one I’m so lost I know I should leave but I moved to a different state with him and been together for 4 years I’m completely heartbroken and shocked he said he asks how their day is to make them feel comfortable sending pictures when I asked why he doesn’t ask for my pictures he said he respects me and can’t look at me like that even tho he loves my body and having sex with me he said that I’m all he’s got and he will change but I’m torn I also asked why he doesn’t look at porn and he said idk I really need advice I have posted this before but I’m really needing advice and I found out more to the story he has been showing more effort since he’s been helping more around the house and said I could look through his phone whenever but I don’t want to live like that I’ve had a boyfriend cheat on me physically and I left and he knows this so emotional cheating is just as bad he also mentioned he never wanted to actually talk to anyone he has one girl on tinder with kids and everything that he blocked because she was getting too personal but how did he even let it get to that point how often was he talking to her . I also never got to read the tinder Convos to see how it was actually happening the thing that’s really bothering me is a few months prior he was saying he wanted me to be more involved with him when I already do everything it was like he was picking fights just to do it then I find all this pretty much from the beginning Of our relationship scattered out til now also another key point is he never had a gf and was a virgin before me and made me wait almost 2 years to have sex but we did other things but he’s so sexual online also in recent times we haven’t been too sexual active because we’ve been really busy I just don’t know if I should move out I picked up my life for his job and we moved out of state please give all the advice !
