I hear you about needing single friends. I haven't gotten there yet.
WRT your H moving out... I found that when I told a couple of key people the word started getting out on its own. It was hard to talk about the first couple of months, and I tried to cover it up, but when I was able to be more honest things became a LOT easier, especially when I had childcare issues and needed help.
I don't know what else to say, but I did want to say I hear you. Have a great day!!!
