I disagree with Labug and wmwb. I think you are allowing him to cake eat. He chose to run, let him go. Let him deal with not having a family anymore. I know it stinks and it means that you don't either, but its kinda true.
Getting your own tree would be a great GAL activity. It would show your kids you are capable of standing on your own. Start a new tradition. Who knows, it might be better than the old.
