Would You Stay If You Weren’t happy?

I been with my bf over a year. I have a hard time trusting someone, so I think it’s causing me to become unhappy. The constant fights, he always blames me when we fight. I get bad anxiety because he calls me names but I love him so much.. I had two other bf’s and one was longer than him so I should be use to pain but I’m so attached maybe because we talked about marriage and all and traveling. But I’m the only one who even drives and he’s about to be 24... I’m starting to loose feelings I think because in the beginning I never even checked out other guys because in a relationship I think your s/o should be more than enough. It’s starting to change honestly I notice other guys more and I’m not a cheater but I think his behavior is making me go. Maybe it’s because I constantly don’t believe him, or accuse him or call him a liar. It’s my fault for getting in a relationship knowing I didn’t trust him. I have his pw’s to social media but whatever he says isn’t enough. I been insecure and hating my body and myself and I’m 5’6 about 135 pounds. I dont know why he made me this way. I never even got fully naked for him... What do y’all think? p.s... No rude comments please.. this is a very rough time for me because I just lost my father and I’m

going through a lot...
