PSA: Don't badmouth your ex to your kids (even when you're mad)
My 10yo repeated something really cruel I said about their mom last week and it destroyed me. I was venting to a friend who was over, thought the kids were upstairs. They weren't. My son looked at me like I was a stranger. I apologized to him AND to his mom, which was humbling as hell. Just wanted to put this out there because I know I'm not the only one who's said stuff I shouldn't have. Your kids love both of you even when you don't love each other. Worth remembering.
This is such important advice. I've caught myself about to vent about my ex right in front of the kids and had to stop. Not worth it, no matter how justified the complaint is.
