I agree with Hammer. Alanon is a great group. You dont have any control over what other people do. You can only make choices. Choices to let your husband know your there for his support and that you trust him to be honest with you. You may be letting your mind run wild in fear which is not healthy for you or your family. Try to live more in the moment and focus on what is actually happening in front of you rather than playing detective. Maybe the key is making sure he never feels guilty or ashmed having to tell you if he slips up. Hang in there!
