I don't get to see her any other time than my court ordered visitation times with her. The X does not go out of her way to facilitate that at all.
Then stick to the court ordered visitation or work out a compromise agreeable to both of you. I would make sure whatever change to the court ordered visitation gives you the same amoutn of visitation and during times you are ok with.
I agree with you that it's not fair for your ex to alter the court ordered visitation and not make amends by a compromise for "make-up" visitation.
