I discovered 14 messages from OM in the past month and I did listen to them and it almost made me want to vomit. He kept saying, "I love you" or "I miss you" or even "I love you, I love you, I love you". One message was about good lawyers he found and another was about apartments he found in her price range. I'm telling you, this nut is in hot blind pursuit of my wife and won't let up and won't stop no matter what anyone tells him. I also took liberty to forward several of the messages to my phone.
Ken, I'm so sorry! I know this is very painful.
Yet...you said in an earlier post that when your WW told you she was going to move out and you said, "I'll miss you," she came back that night and asked what it would take to make the marriage work.
It sounds like she is VERY conflicted. She likes the attention from OM, but it sounds like he's pushing her into this rather than enticing her into it. If she really wanted to go, she'd be gone.
I say continue to be friendly but also maintain the distance. Continue family activities without her. If OW keeps hounding her like this and you remain calm, cool, and collected, his hot pursuit is going to wear thin fast.
As for the cell phone...I don't know who your provider is, but since your WW refuses to get a new number, perhaps you could block OM's # so they can't call each other. Just a thought --
