We're very close in our situations as far as living "together" and the divorce possibility. In my case I'm the one on the couch. Mine too is threatening D, but she hasn't filed yet. I said the exact same things you did about not supporting it.
Glad you're posting here. I only started again recently and I already feel better and have gotten some great advice.
What's really eating at you the most right now? It helped me to talk about some of the specific stresses/fears I was dealing with (pick 1 or 2 to start) and begin getting them under control. They were consuming me. The people here have been great! How are you feeling physically? Sleeping? Eating?
