Had known him and is wife & kids for 10 years. The guy had serious depression and I was talked with him once in a while to cheer him up.
I had also had a lot of opportunity to talk to his wife because she was friends with my wife and would come over nearly every day. So I know both sides of the story very well
On this last visit I finally unlocked one of the reasons he was having trouble climbing out of this depression. His wife was a secret NPD. (fairly mild as far as we go but enough to make it conclusive.)
So I knew a few modifications that they could do and make it work for them. I called them both up, sent them e-mails and told them to meet up with me on the weekend. I was going to save their marriage!! (so I thought)
I finally got back an angry message, "I will consider any further correspondence between you, me or my wife as harassment."
Saying I was really sorry I crossed the line didn't help,... so for now on NC.
oh well. Let the N eat my friend alive.
