I agree with IH, you're staying on the right track. Stick with NC unless it's about the kids. She's not repentant yet, she's just throwing lures at you to try and hook you. If she does she'll never reel you in, she'll be content to leave you dangling on the line. She's got to think she may really lose you and she's not there yet. You are right, she continues to be disrespectful and defiant.
