Need some support

Just so you know for informational sake...divorces can be written with provisions, etc. I was covered with health insurance through my ex husband provided he did not lose a job through fault. It can be written in there. My consideration was having MS and at that time needing expensive but covered medications which I am no longer on anyways as switching meds and the side effects were worse than the illness which has been in remission. Neither here nor there but I want it clear to anyone reading, yourself included, that don't let the fear of certain marital benefits such as health insurance coverage hold you back from taking such a step which for some may be necessary.

If he is unable to be alone, than your depression - a sort of abandoning him into your dark inner world - might have prepared for that, too.

That would make sense that he would line up a replacement to fill the role that he has to have by his side. But what a shame, given that all in all your marriage was more good than bad, considering how horrendous some other marriages ended up out there.
