Phil,
I get the sense that this is a never ending game of one-up-manship between both you and W. Both of you "have" to be right. Mostly you, I'm thinking.

Take yourself out of this mess. If she's crazy, why do you let her get under your skin and argue back with her. It's futile. My opinion is that you look for reasons to text her numerous times during the day. Stop it. Be the bigger person. Be the one your kids can emulate and act like an adult. Forget about what she does.

BTW, if you talk to your W the way you talk to some of the peeps here, I can understand why she wants to run away. This is a "help" board and if someone doesn't agree with you, you turn on them and treat them the way it appears you treat your W. I give Phoenix a lot of credit for "still" trying to give you good advice in spite of the treatment he/she's gotten from you.

Listen up, you're getting good advice, just refusing to take it. As Dr Phil says, "How's that working for ya?" Not good,from what you still post.
