So I've sat here and written and re-written three times, trying to find some words of comfort to share. The biotch of it is, I don't believe there is any, or very little. What there is, is that your son includes you in his life and the life of his children. THAT's the only hook to hang your hat on in this one. But then, that is a very important hook, isn't it? Somehow, you just have to be satisfied that during the entire meal, everyone, from H to OW on down were very aware of the 'GHOST' in the room. Or rather, not in the room.
It's just another of those times when you wish things were more like in the movies and you left all your heartaches at the door when you signed the papers. I think that, as a mother, the pain and awkwardness that it causes our family is the deepest pain of all for us.
We just have to keep chugging along. That is what I tell myself everytime when I make the effort to contact my steps and visit with the kids, bring little gifts for the Holidays, etc.
Seeking, you have proven yourself to be a strong and loving individual. Try not to doubt yourself or your contribution to the family you love. They don't.
