She probably told my daughter she would talk to me about it, which makes me the bad guy.
It's up to you how much you want to coordinate with your ex. I prefer a simple custody schedule. My kids stay with me on my days. My kids talk to me if they're uncomfortable about something at my home. I do my best. Yes, sometimes S or D was dragged to their sibling's events and had to watch, read, or play games. That's life as a single parent. I didn't think it was a big deal that they had to find a way to entertain themselves. Now, fortunately, they're mature enough to stay home for an hour or two alone.
There's also nothing wrong with being BFFs with your ex-wife. My brother is divorced and he and his wife regularly hang out with his ex-wife and her new husband. They even entered a business together. It took a few years of separation, but it's a cozy arrangement now, with truly no tension between them.
