I’ve caught my husband

I’m 22 weeks pregnant with my 3rd. My husband in the past has used reddit to look at porn and I thought that was over but today, I caught him looking at stuff that I never thought he’d look at (again). He hides his searches, so there’s no way for me to confront him. I’m just over feeling like I’m not good enough. I’ll never be when he looks at unrealistic pictures of women. I’m sorry, I’ll never be. It’s not even abt looks for me anymore…Jennifer Lopez, Shakira, the kardashians, etc…all got cheated on and they’re beautiful, which makes me think it’s not abt looks after all? Idk. I seriously want to leave him, but I’m pregnant with my 3rd and don’t have a job. I feel so stuck. My husband in the past did a lot of secretive things that weren’t right and we fought endlessly over it for years bc it left me so insecure. I’m back there again and I’m pregnant. Lovely for me to be a single parent with a brand new baby next year…who’s gonna want that. I’m just depressed and already been crying abt it. How do I act normal without wanting to hate him?
