WeI were arguing last night and I guess I pushed a button that pushed him over the edge and he hit me,in the face. After 18 years of marriage I can't leave, I love him. This is the first time this has ever happened. He apologized and told me he felt ashamed and would never cross that line again. What do I do? He thinks anger management classes are over the top for one incident. I'm devastated. He has always been the perfect husband, always.
