TAL pointed something out. What do you do when you don't have the boys? I know (boy do I know...) money is tight all around, but what do you do when your wife has the boys? List me a few things that you would like to do and promise to do one in the next couple of weeks.
I am so glad your W reached out to your mom again (even if it was with sil's guiding hand). My H has closed himself off to my family, never asks about them, like that your W. I guess that have to do this, huh?
Reconsider the AD's.
PS: I am so sorry you are so tight on money. Its an awful feeling and tends to cloud all my thoughts. Wish I could write you a big check to lift some burden!
