One last piece of advice. The OM your coworker is not your friend. You should disconnect from him completely. That will make him far more uncomfortable than you confronting him. If you can move work spots away from him ask to do so. You need to treat him like a complete stranger. Don't be mean to him. Don't be rude to him. Don't confront him. Just treat him like he's doesn't exist. Over time you will start to feel it in your heart. You may have to act for the first while but acting turns into true feeling if you do it long enough. He will probably mention it to.you wife if she says anything about it deflect it. You're your own person you have the right to choose your friends and the people you care about.
