First BD was 4 1/2 yrs ago, telling me he was very, very unhappy. That we had nothing in common and he couldn't see himself being retired with me. My response was "who is she?!" Doesn't seem to have been an alienator at that point. Tried MC by myself and things improved somewhat, but that's around the time he started tailgating with a lot of rowdy younger guys at the football games. They were all at least 15 yrs younger than H, who was 50 at the time.
BD 2 & 3, 12/10 ended up a 2 wk separation at my suggestion, came back for 6 weeks only to leave again because he just wasn't happy. Had been having an EA with a gym instructor for more than a yr at that point. So in hindsight I may be almost 5 yrs into this S**t.
