I think that you are trying hard to cope and doing the best you can under the circmstances.
Perhaps you and your Husband can work something out regarding the children's "extras". Perhaps work out a budget that you can both afford WITHOUT letting the kids know that they are a financial brden and without blaming the other parent.
With kids there are always extras that come up and for some reason they think we can just pull money out of our arse.
You are going to be Ok, just try to deal with one day at a time.
And don't forget to breathe!
Have a fantastic weekend away.

There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
