Well, OM called W yesterday. I guess it was too much to hope that he wouldn't contact her again. He's trying to get out of the army and wants W to write a letter about what the recruiter told him during his enlistment (which I'm confident won't work, by the way). He also tried to (as she put it) "sweet-talk" her into getting back together with him.
W unloaded on him, calling him every name she could think of. OM asked her if she had slept with me, and she said that she had ... sending OM into a tantrum. W was gleeful as she told me this, saying that "it's his turn to suffer."
All this is obviously better than her taking him back, but I'm very uncomfortable, though I didn't express that to her.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
