Hi NLT. I agree with Forever - you did really well, especially with that conversation coming out of left field like that. His crazy OW will probably be pushing him to file, but hold strong and delay if he does. She's using him. And is crazy. She will drive him crazy too. Their relationship has no solid basis and is doomed to fall apart. 

Hang in there, and keep wearing those rings.
