I'm so lost help!

My husband is abusive I have a daughter with him but I have zero confidence because he's gotten so far in my head. I don't know if I should leave him but if I do I know I won't have the strength to stay out of his hooks to reel me back in unless I'm in a stable relationship where I feel loved and worth something and am happy but I feel like nobody will ever want me. I have a crush on a guy but I don't know how he will react to me confessing my attraction to him should I pour my heart out to him and ask him for advice should I leave it alone I feel worse that every time I see him I get butterflies but I'm married I feel like I'm cheating I'm so confused idk what to do I know what I want but I'm too afraid to take a chance and get trampled my dad just died so I'm still grieving my husband doesn't help I want to leave him but can't because I have no money and I am not strong enough without having a happy stable relationship first. I feel lost and hopeless worthless I feel like a bad mom I can't do anything right I just need some advice please 🙏😭😭
