SO sorry your kids are going thru this. I am glad my kids were grown when this happened to us. However my husbands' low was unbelievable to me too. We lost our 21yr old son 3yrs ago. He is now calling friends telling them he wasnt his father! I was feeling sorry for him, but after that I have no feeling for him at all. It is unreal to me how fathers can just ditch their children to suit their own needs.
My ex is a very confusing person. Some days he is easy to talk to, and kind, and reasonable...other days he is angry at everything, and belligerent, and unreasonable.
