I can relate to so many of the things in your situation. My Mum died last October (and her sister three days earlier, the aunt I visited last summer). It's hard not to feel almost completely abandoned sometimes. But this morning, my daughter woke up in the most sweet mood and I thought, be grateful for what you DO have, Livnlearn.
Good on you for getting your work published, and getting the teaching work. There are times in between the despair when I feel exhiliaration at being independent, inspite of financial precariousness, as I am sure you do.
Throughout all this, what has been your H's official line? That he is working on things? Or is he openly stating he is not coming back?
I'm in a similar place of confusion about how much longer I want to put effort into DBing the M.
Good to see you back though (if you know what I mean!)
