I think you have every right to be upset with this man talking to your son. You don't get to screw my W and then come around my family as if nothing happened. OM should have had enough respect to stay away from your son. If he can't respect that boundary, then you may need to tell your children you stay away from him due to him being inappropriate. You don't have to tell about the A. But your children are old enough to know that OM is bad news.
