If you confront him, he will manage to not only maneuver his way out of this, but will make YOU feel bad about even having such thoughts of him! Been there, done that. The last time my AH went out with the boys (while in recovery), I accidentally found pictures of a woman on his camera. Couple of normal pics and one "butt" view. Whoever took the picture was obviously enjoying her rear end. When I confronted AH, he said the camera was out on the table with several others and one of his buddies must have taken the shot. Do I believe it? Yes and no. It's plausable, but I certainly don't believe him 100%. I guess, one or two "little incidents" can be explained away, but when it happens several times-- I would trust my gut. Whether drinking or not, it's unacceptable. If he wants to "socialize", let him, just remember to remove yourself from the picture.
And, to your earlier post, being strong is really overrated
