Went to a pumpkin carving party that the whole family goes to each year. H did not come. Was totally depressed watching all the families with small kids - all of them with two parents by their sides. I felt like a total failure.
Ack - where's the PMA?
YOU are not the failure. You were there for the kids and you are not walking out on your M. I don't say that to throw stones at your H, but to help underscore what you already know.
You have to make your own PMA. What's something fun you can do today with the kids? Do you cook? Bake cupcakes with them. Or, if it's warm where you are, go to a park and have a picnic lunch.
Resign yourself to have fun with or without H's participation.
