Since you are undecided, what about going to a marriage counselor and seeing what options you might want to look at? I don't know the complete story of 27 years but that's a long time and something must have kept you together. You say he's not a bad guy. But only you can decide on what to do with the rest of your life. I think a good counselor or couples counseling can help you a lot. I've seen it help others decide what to do. Best wishes to you. CQ
PS. Welcome to the forums and hope you'll keep posting and reading. Lot of good folks here who care to "listen."
