That’s a tough one Hurt. If it were me, I would respond because she asked you a question about the kids. I would keep it short. “Yes, good day” and “no pictures” and leave it at that. Not responding to a direct question, IMO, is passive aggressive. Yes she did all those things and the check in is only disrespectful because you know what she is doing. If you didn’t have a spy, you wouldn’t. Honestly...she is going to do what she is going to do and you can’t control that. You can control the flow of info that is only going to fuel your hurt and anger in the end and keep you tied to her emotionally. If you are committed to keeping things amicable when it comes to coparenting your children, I would try to limit the amount of intel you are privy to and focus on you GAL activities and spending quality time with your kids. Others may have different advice, IDK, but that is how I see things.
