My confidence is at the bottom right now. I've been with my husband for 23yrs married for 13yrs. In the beginning of our relationship we had alot of issues. He was not nice to me, called chat lines, even went to a massage parlor for happy ending, used to stare at other women even broke up with me for a few months to sleep with another girl. We ended up getting back together. We'll occasionally chat online and look at porn. Went to a strip club and lied about it. Excessive drinking too...not.really sure what else he did but one day out of anger and hurt 17yrs ago I slept on a one night stand.. more like a 5 min stand. I never told him and now we have a loving and good relationship for the last 15yrs and he has apologized for all those years of being mean to me. Well now 18yrs later I suddenly feel guilty about it. I don't know what to do. I feel like if I tell him it will ruin our relationship. I feel like maybe just trying to forget about it and move on. What would you do?
