Reading your post made my own gut wrench in sympathy. I forgave two incidents of infidelity because I attributed it to alcohol. It amazed me that I was able to forgive -- and yes, mostly forget. The third incident was an earthquake that left the landscape of my marriage in rubble. Forgive yes, forget never. I sincerely hope your husband's alcoholism is the cause and he is not a cheater in his core being. I get the impression that sobriety does bring an end to cheating in some cases . . .so . . .here's hoping.
