This is what I do. I fret over things until I decide in my head that it's going to be okay. My first concern was money. In hindsight WAH was starving me out so the kids would live with him. I bought into WAH's script that I'd be kicked to the side of the road, abandoned by my entire family. Oh he'd set me up in an apartment so I wouldn't be homeless but the rest was on me. The kids would of course visit you know when they weren't busy.
Didn't play out this way because I'm their mom. My two older kids moved in with me and have offered to do whatever it takes. If push came to shove they'd get jobs and help buy groceries. They aren't going to leave me hanging regardless of what WAH wants. I'm not worried about money anymore.
