I think that when you come from a place of doing what is best for the children, you can't go wrong. If you are struggling financially, then your children are struggling as well and your H needs to step up. If he won't do it willingly, then it is your obligation to take action.
So stop beating yourself up for this. Maybe it is the wake-up call your H needs to get his rear end in gear.
Hang in there!

It's easy to find our bottom, it is our top that requires cultivation.
Every rough spot adds to our emotional constitution. -Barney Fife
