Well, I screwed it up a bit, but no one is perfect and I forgive myself. LOL.
I called OWH to let him know I was going to do the confrontation and that I would not mention him or that we had talked. I forgot to *67 the call and she picked up his cell. Not expecting it, I hung up and immediately called her cell. She did not answer. I called their house, no answer. Back to her cell, now she's calling back on his phone, but I'm trying to get a hold of her on the cell. Debacle.
Anyway, I didn't want to leave "evidence" of what I said so she'd be able to play the voice message for H, but I just did it anyway. Very calmly I told her all I said above, making sure infidelity was in there plenty, and work on your own M, and leave mine alone, and this is MY family. Etc. I did well, but just wish I hadn't lost the element of surprise and screwed it up.
Can't wait to hear from DH to see what he thinks about all of this. We saw each other leaving for lunch and he never even said hello. He did look very, very bothered, huge scowl on his face.
