There's a few possibilities- one is simply that you are observing his fantasies as he has sex with his wife, or that he indeed is having sex with other women while married. I don't know if a neg has to be involved at all, since you do have feelings for him (as what I get from your post). I would suspect neg involvement if these visions cause you to become upset (or needy for him) but if you're a disinterested observer, then I tend to think that it's your subconscious providing you with the motivation to point 'over there'. He might also be thinking of you, causing you to hone in on him also- lots of possibilities, or combinations of either.
