You can seek modifications to the visitation. Call your lawyer or ask for referals for one who is good and reasonably priced if you don't have one.
The good thing is that with your daughter being 11 1/2 she can have input. The magic age is 12. The courts probably wont stop Dad's visitation but they can and probably will require that he take her to her school activities. That is part of parenting. It is not mandatory for you to drive 1/2 way under 100 miles...unless that was written up in the court orders. If it isn't written up then follow the pick up & drop off orders as they are written. If they are suppose to pick up at your house and don't do that then don't bring her 1/2 way. This will force dad to bring the issue to court & allow you time to respond.
Remember not to go into the court room angry at all dad doesn't do. Keep your focus on your daughter and what is important for her well being and development. Bring letters from her coaches & teachers if at all possible that show who has been at her functions and how being involved in school has helped in her development. Also if anyone other than you, your daughter, the ex & his wife know of how you have gone 1/2 way to take her to all of her visits and activities get them to testify or write letters as well. Documentation on your willingness to work it out are important.
Good luck and hopefully this all gets settled for you and your daughter soon.
