I also suspect my RAH of cheating on me about 5 years ago, no actual proof just a gut feeling and circumstantial evidence. I know he would never tell me the truth because he knows what I will do because alcoholism is one thing but cheating is just going too far, drunk or otherwise. So, I am letting sleeping dogs lie but it is something I want to address when he has more time under his belt sober. The thoughts used to consume me, not so much anymore. Time and inner peace is a great healer.
