Barb - I'm so sorry. It must be a shock for you to see it so blatantly.
My H shared a lot of naked pics with I don't know how many women on the internet - facebook friends, whatever. While we were living together and supposedly trying to work things out. So, I definitely can relate.

But, I'm curious. Why did you re-friend him? Why put yourself through that? Unfriend him, and block. You don't need to cause yourself more anxiety. I also wonder why you are still tracking your H? I would recommend deleting that app immediately. It will only drive to crazy and it can become obsessive. I know. I was there.

I can understand you need communication and cooperation from your H about the refi, but just keep it all business. It's for your own sanity.
