So I cheated on my husband about 20 years ago and since then I have been faithful besides texting with a friend ( of the opposite sex ) about our problems. No lines were crossed there, but he felt there was. Now we have been married for 23 years and he always brings it up and he says he doesn't trust me and he feels like I'm not telling him everything although I am. He just makes me feel so worthless sometimes, but I know that it's just the pain I caused him in the past. What should I do?
