Cheating with a married man

My husband recently started a new job and has met new friends. Recently, the families all got together for a weekend. Much to my surprise, this new co-worker and I hit it off amazingly. He to is obviously married with children about the same age as mine. We have talked many hours since our meeting and he has filled me in on the past 2 years of his marriage and I have discussed parts of my maritial problems. Needless to say we are both basically staying in our marriages for our childrens’ sake. My husband and I have grown apart over the past 3 years and my “new friends” just as unhappy as I if not even more unhappy. I don’t know what exactly to do with this whole situation. I always swore I would never cheat on my spouse but this is so much more than “jumping into bed”. We can sit and talk for hours and I feel more comfortable talking with him than I do with my husband of 7 years. I know we shouldn’t even be considering this, but he and I are considering trying to keep our relationship alive until our children are old enough to understand. Please help, I have no one else to talk with.
