I am sorry you are feeling this way. I think you handled the conversation with your son perfectly, so you should take some comfort in this.
As B mentioned, the pain and sadness that you are feeling will begin to get better IF YOU allow it too. By this I mean, that you feel it, you grievve it and then you let it go. Will it come back...yes it will but each time I think it gets a little better.
As hard as this can be you must try and learn from this - not just for you BUT for your children AND your H.
Sending you cyber hugs ((()))
God Bless Eric
