He has thrown himself into new relationship. She has three children and seems from twitter quite sensible, well educated etc, but has launched into relationship statuses on Facebook after only a couple of months. Has was EA since I had DS, progressed to a bit of physical stuff in last few years. He is in army and their welfare service reported him to SS, although no action was taken as I was about to move out by then. Feel I should tell her. Or should I but out?
