Please help I’m in a bad relationship

So I been with this guy for over a month. And he did something to me 3 days ago I can’t fucking forgive for. I’m hurt I’m always upset. Even cuddling. I don’t enjoy anything with him anymore. It’s a controlling relationship. And is toxic I do believe. But me being me I’m in this still. Now I’m jealously and protective and like that okay. So he said he wouldn’t like anybody’s pics, comment nothing that I wouldn’t like. And I wasn’t aloud to have streaks. He’s also told me that there was nothing on his phone I wouldn’t like.

Well outta a month I checked it two times and I found a snapchat subscription of nudes of girls, and the second him favouriting younger girls nudes, but only two pics of one girl. I immediately left when I saw and he cried outside my house, he broke his phone. He wouldn’t leave. Knocked on my door. Everything.

He said he would fix it. I said there was no trust and what he did to me. Shit like that. Well he wouldn’t stop, than after I calmed down he took me out to supper and spent 80$ on my meal. I’m still not over it. I’m still not happy. I can’t even deal with him being on his phone. I get anxiety my eye has even started twitching. He don’t even tell me goodnight or I love you before bed and I sleep over every night , we spent days together even working right after. I’m to hurt to be with him. But I’m so mentally unstable I can’t leave. Help me.. I enjoy nothing with him.
