I (31f) looked at my boyfriends (34m) phone and ruined our relationship

We’ve been dating for 9 months at the dismay of a group of friends he and I share. I found out he’s been lying about so many things, and I’m just at the point of going numb honestly. I knew I broke his trust, well, to be fair we gave each other our passcodes but I don’t think he’s dug as deep into his phone as I have his. Last night I spent hours discovering that he is still messaging women on Snapchat he finds attractive and is receiving messages back, he’s lying about when he’s getting out of work, he’s lying about who he’s tried to date in our friend group in the past. I should have seen the signs early on, but I was just so hopeful that I’d find someone genuine. I saw the sentiments he expressed with his friends that in the beginning I was “clingy” and “too attached” (in reality, I was considering us a casual fling at first, and he was the pushy one.) He’s put down my appearance to my face, he’s love bombed and then ghosted me, and tried to make me burn my bridges with two people already. I can’t help but feel anguished and numb. I have no where else to go at the moment and don’t know what to do. I’m thankfully now working in a moderately well paying job but at the moment I don’t have the option to up and leave his place (I had to escape an awful and abusive living situation by living with him). I just don’t really know where to go from here. I really don’t think I’ll ever trust a man again.
