hrmm... well you have to consider your intensions before you tell him how you feel. because i personally think that you should tell him, but that is besides the point.

i know that you want him to feel how you feel now, but he is engaged. he has already moved on with that part of his life and more than likely, you'll get shut down. however, i suggest that you tell him something along these lines, "i know that it's in the past now, but i always looked at you as more than a friend. it's still true to this day, however i know that you're happy as i value your happiness very dearly" hell, i dunno, but something along those lines. it will tell him how you feel, and at the same time, it won't leave him feeling as though you're trying to steal him away.
