is your wife involved with another person already?
I think it was an EA for a while, but they said they were just sharing their problems. Both having marital issues. Met in December, not much going on until late march - mid may. then texts and call were pretty numerous. EA's wife called me and left a voice mail and then called back. I got phone records and confronted her. She said she wouldn't be calling him anymore and I don't think she has, but I don't know because she may be calling from her work phone. His wife is watching closely.
Whe she told me she was going to file, she said she had made the decision to file before I found out about the EA, but I don't know if that is really true. She was waiting for the kids to be out of school before she told me/them.
