Bloody hell, this sucks!!!! (Sorry again, Heavenly Father.) Shouldn't being officially separated count for anything? It's as good as divorced. WTF is wrong with your so-called H --- he is not worthy of that title or that of father. I hope OW screws him over something awful. (Oh, Lord, I shouldn't hope for pain to be inflicted on another, but perhaps it will be a learning experience for your H.)
Just do the best you can, Hmama! Perhaps filing for bankrupcy could be an option? Just throwing it out there.
