Welcome and glad you're here Jennygirl--
Just one thing: I wish I were a child of divorce. Instead, I'm a child of alcoholics.
Ditto Givelove, from another child of an alcoholic -- and a currently very very happily divorced single mom with 2 thriving children!!
The things you are dealing with and sharing here are big decisions, big themes, tough stuff. But try to keep an open mind. I find that when I just surrender my false sense of control or beliefs then new paths open up. It may not be easy but it is worth it!
Can you try an AlAnon meeting? Find a neighbor/mom you can swap childcare hours with?
Baby steps still get me moving in a new direction and ultimately lead to bigger positive shifts....one day at a time--
Peace-
B.
