I cracked one time when my father asked on the phone how things were going as he saw a stream of pics on his FB newsfeed of my H with other girls.
So I broke down in tears and told my dad most everything.
I was sorry later, but what I did was, I just told him that I wasn't comfortable talking more about what happened or was happening on a regular basis. I just explained that it all came out but wasn't interested in feeding him an ongoing stream of what was happening. And he respected that.
And occasionally I would give him abbreviated updates. I did ask him not to elminate my H from family communication (emails) but my parents chose to do that anyway b/c they said he wasn't treating me as a man should treat their daughter and was flaunting his party lifestyle. And I had to respect that choice of theirs also. So it can get icky.
This year, my parents called me this month and asked if they should send an anniversary card to us. I felt that was very kind to me. And I was glad I could say yes, send one.
Since you asked for suggestions...that would be mine. Explain that you cracked and needed to talk, but just ask for prayers from her and know that you could give her small updates as they come along, but in general, you'll be keeping the particulars of the R with W private, from your POV. Just an idea.
