I didn't see any questions about this specific topic in my searches so I'm posting here hoping for some divorce/custody advice.

I've been divorced for 11 years. My ex and I share 50/50 custody with a daughter who is now 14 and a freshman in HS. I don't live in the same town where my ex lives (30 min away) and my daughter goes to school in her town. The issue is that lately, my daughter has begun getting invited to parties/sleepovers/activities at friends' houses on weeknight evenings (some Fridays, too) when it's my parenting time. Of course she wants to go even though we typically have a great time together. If she does go, that means I lose my evening parenting time.

This issue came up a bit in middle school but, I was able to either just say no and shut it down or we would reschedule a day/night for parenting time at a later date. Now, however, under the influence of her mom, she is saying that she should be allowed to go even during my parenting time and that, further, we shouldn't have to reschedule the parenting time for a later date.

I don't want my daughter to start resenting coming to my house (especially because I know that soon enough she'll be able to dictate where and when she goes anywhere) but, I also want to maintain the custody time I have with her for as long as possible, since her mom's household doesn't set the best example for her. None of this would be an issue if her mom wasn't in my daughter's ear about it so, I am also coming up against the shitty influence of my ex. Anyone face issues with older children who start bucking the custody arrangement and are supported in this by their moms? What actions should I take, if any?
