Q&A How Do I Know If My Mate Truly Is Safe?

I know my husband has had sex with a man in the past and still enjoys homosexual pornography, in addition to heterosexual pornography. He also had an affair with a woman that was very emotional and physical. He says he regrets the affair and doesn't want to be with men. He says it is a turn on for him, but not something he acts out. I would prefer he not watch any pornography at all, especially now. I don't know how to feel safe in this relationship with so many revelations of things I did not know about him. I feel like I don't know him at all, maybe I never have. He's never let me know him. He had sex with another woman and wanted to leave me for her. He is committed now, but how do I know that is sustainable and true? How do I know he won't change his mind again? How do I know I am enough or that he will ever truly open up all his feelings and vulnerabilities with me?
