Guess that's an EA, and I sure do feel back at square 1.
A week ago I got our cell phone bill, and I've always paid for the full detail on H's phone (no other family members). Trust but verify. Many, many texts to one number, starting around T'giving. It was not pretty when he came home, but I was the one who was "creepy" for looking at his phone.
Just before he came home, very late, I had called the number. A female answered, youngish sounding, denied, all those calls were mis-listings, didn't know what I was talking about, vaguely "knew" my H etc., etc., but apparently cold turkey she's stopped texting him and responding to his after that. Today I got the next phone bill, and while it verifies that the texting stopped the day I confronted, it also shows ramping up to double the texts from the first month to this last one.
He won't discuss, tell me anything about her or the relationship other than "she was someone I could talk to." Every 10 minutes for 11 hours??? And he's a municipal employee. I cannot imagine it didn't impact his productivity, or what would happen if this came to light.
Our MC called him out very clearly, told him straight out no "private" relationships outside the M. All H wants to do is forget about it, and make sure I do, too. I think this has doused the last ember of hope I had.
