I think you already have the answers yourself and know what you need to do. You already know you're accepting less than what you should; you know that he is treating you like second fiddle and second choice; you see all the red flags; you know he is saying just what he needs to say in order to keep you hooked in. Now you just need to pull off that bandaid and walk away from him. You deserve better. Never let anyone treat you like you're second choice or second fiddle. You deserve to be treated like you're #1 in a person's life. Cut this man loose, and walk away with your dignity and pride, is my advice! Wishing you all the best.
