It is hard on us but much harder on the kids. Just let your kids know you are there for them. Spend as much time with them as possible. They will soon realize no matter what happens between you and their mother, you will still be there for them. Their fear is losing you.
Watch your son regarding his "moods". Maybe he needs to talk with someone who is not linked to the situation. My kids are older but they had problems dealing with it and both got very depressed. Gave them each a notebook to write their feelings down. It helped a lot.
It is hard to not have feelings for someone you loved for so long. I will admit that it does somewhat go away. I can say I am over my xh for good. It was a long battle but I have reached the end of my rope with him. I got tired of hanging on. I let go and feel free now. I am beginning my new life and so far it is great.
