As hard as it is to do - be patient. And like one reply said - believe half of what you see and none of what you hear. Also, limit your advice requests to this board and a marriage counselor.Surprising as this may seem - your friends will get you in bad shape with bad advice. They will tell you what they think you want to hear and confuse empathy with advice. If H is having an A, chances are it will not last long, and it will offer an opportunity to realize howimportant you and his family are. This A could be an opportunity to fix your marriage. Be hopeful, pray a lot, be patient, and resist temptation to do anything stupid like confronting without any more real info. Confront him only if you have to - i.e. if he makes it public. I am pulling for you.
