I was deeply involved with another man for many years. He was my go to person because I thought my H was unsympathetic. He moved away with little warning and I was destroyed partly because I thought I would now have nobody to talk to. I turned to my H and he came through. Now we have a stronger relationship than we ever had and I find I don't even think about the other man. Believe me when I say we were involved for a long time too. Give your spouse a chance.
