Custody (Holiday Schedule) Frustration
So for context, I've been divorced for almost 2 years, with our custody agreement just recently hitting the full one year since we got divorced. We share a 7yo daughter, and he sees his daughter once a week for 2.5 days (Sunday night-Tuesday). Once a year, my ex and I talk about school holidays and how we want to divide up the time equally. I'm looking for advice on a situation involving holidays/school breaks
It is almost that time of year where we have to discuss holidays, so that we can make plans accordingly (our daughter gets 4 major school breaks; one in November, one in December, one in February, and one in April). Here is the problem: he has not stuck to a single agreed on break for one reason or another. He originally was supposed to take her for the entirety of Thanksgiving break last year, and two weeks before the break told me he could only take her for 1 day, the actual holiday. I was traveling out of the area for the holiday, and because he couldn't take her, he gave up that whole week of time with her. (Didn't mind at all, loved having her with us). But then he was supposed to take her for one week for Christmas break, and told me he would only take her for 3 days because he had a vacation planned that our daughter wasn't invited to. He also breached our agreement and for her break in February (she gets one week there too), he lied to me and said that he had her, only to backtrack and admit that he had other people watching her due to his schedule.
It is getting really frustrating, because every single long-term break that he has been given, he either does not take her for one reason or another (frequently with less than one week of communication) or lies about taking her. I am getting more and more wary about it, because he wants me to give him the week of Christmas, Spring Break, and a break in November. Is it considered being "a jerk" if I told him that I wanted to stick to the schedule from last year due to his inability to commit to a consistent visitation schedule that we had agreed to? I don't really want to give up Christmas Day, can absolutely understand why he would want it, but I do want him to take some kind of responsibility/accountability for his decisions to not take her for scheduled time.
Any advice/guidance is so greatly appreciated. I feel really lost and frustrated on it.
