If you go back a few days of posting, I warned you. All of the signs were there of her turning the D proceedings ugly. This is why I wanted you to prepare yourself for that. It happens in most Ds for a variety of reasons (immoral lawyers, bad advice from friends, one disagreement over a minor issue causing one party to begin reneging or disagreeing on things previously agreed on, etc). Your WAW was showing signs of being capable of turning this ugly, and you are already starting to see that playing out.
Her cheating on her BF (I presume with you) was a huge red-flag. If they will cheat with you, they'll cheat on you. (I may have read this before but for some reason it didn't stick with me until you repeated it here.)
