That's an impossible situation, which is what I initially faced with my husband. He refused to acknowledge that he has an anger/rage problem for the entire last year.

I saw the red flags too before I married, and I married anyways. I beat myself up over that fact for a long time. Then I came to a place of greater acceptance -- it is what it is, and I made the decision that I felt was right at the time of marriage. We have to forgive ourselves for getting ourselves into a less than ideal and hurtful situation. And we learn the hard way that red flags mean trouble ahead. But don't beat yourself up.... either the situation improves, OR if not, you will have a tough decision to make. I don't think or believe you truly want to feel miserable and unhappy in a marriage for the rest of your life. I know I do not.
