What can I do when my co-parent treats the custody schedule as optional?
Quick answer
A custody order is a plan both parents are supposed to follow, not a starting point for constant renegotiation. When one parent treats their time as fixed and yours as flexible, here is how to hold the line while still looking reasonable.

Your parenting time is not a favor you owe
A custody order gives each parent specific time, and you are allowed to keep plans you made on your days. Declining a swap because you already scheduled something with the kids is not a refusal to co-parent. It is you following the same order both of you agreed to.
Guilt language like "you are not doing what is best for them" is a common pressure tactic. You can accommodate a genuine emergency and still say no to a routine travel conflict without being the difficult one.
Make swaps even, in writing
When you do give up time, agree on the make-up days in the same message before you say yes, not after. If the other parent cannot commit to returning the time, that is useful information and a fair reason to decline.
Keep the arrangement in text or email so there is a clear record. A short, neutral reply like "I can cover those two days if I get my regular Tuesday-Wednesday the following week" documents that you offered a reasonable trade.
Ask the kids question is worth addressing directly
Floating a trip to the kids before clearing it with you puts you in the position of being the one who says no. You are right to ask that plans touching your parenting time be run past you first.
Put the request in writing once, plainly: "Please check with me before mentioning trips that fall on my days." If it keeps happening, that pattern is something a judge or mediator can see in the message history.
When the pattern does not stop
If accommodation requests have become an expectation and your time is quietly eroding, start a simple log: date, what was asked, what you agreed to, and whether it was ever made up. Patterns matter more than any single incident.
Persistent problems can be raised in mediation or, if needed, by asking the court to clarify or enforce the existing schedule. Knowing exactly what your current order says, day by day, is the first step, and a schedule calculator can help you map it out.
