Don't give yourself too hard a time, unfaithful- you ended it, you feel bad about it, personally I think you should let it go, unless it underlines current problems in the relationship. My dh is in the navy, and away a lot. I trust him- about 98%. I understand he might one day be drunk and stupid. I'd rather not know, cos if I knew I'd hav eto deal with it, and that would mean either leaving, when we really do love each other, or a whole new realm of hurt and trying to rebuild. if you are sure it was a mad moment, might be better to put it behind you, if you can. Don't get me wrong, if it was me, it would eat me up, but that's part of the penance, isn't it?
