Quote: No gift, it's time to let go. If he wanted a gift from the kids through you, he should have stayed in the M. If the day comes where things change and the two of you work things out, then the gifts can start again.
I am sorry, I disagree. Easy way out of this is ask the kids what they want to do. If they don't want to get a gift then that is fine. If they do, give them the money to get it. Or let them "earn" the money by doing a couple things around the house. This way it will be their money and not yours. Leave the decision up to the kids. Don't punish them by not letting them get their dad something.
I know you said he doesn't buy you anything....that is fine. If you think it hurts the kids feelings by not having something for you under the tree or whatever, give them some money to buy you something. I do this. I don't care that I am paying for my own gift, it makes the kids feel good and whatever makes them happy, makes me happy.
It is really up to how you want to handle this. Just let the kids decide for you.
