Just so you know, how I am dealing with my stbx is the same as how he appears to be dealing with you.

Frankly, I want nothing to do with my stbx. I have gone as dark as possible. We have custody arrangements and I stick to them. Nothing more, nothing less. If she attempts to engage me for any reason, I ignore it.

I want nothing to do with her and I don't want her to chase me. I'm done.

And that... sounds to me like the possible reasons for his behaviour. He's setting his boundaries with you. He's not playing a game.

To be a little more clear about this, my stbx has set up the kid schedule. Something that I asked for because without it, I saw the kids very little. All based on a schedule that stbx created, without discussing it with me. Her L drafted the schedule, along with the separation agreement. Because I knew I would not be able to "negotiate" with stbx, I agreed to the schedule because, it was certainly much better than prior and it was at least "close to fair".

And... once it was signed, my W then verbally asked / suggested / stated that she wanted us to be flexible. So... in her mind, it was back down to her way or the highway, for my visits with the kids. She would ask for a change in the schedule and I would say, "OK". I asked for a change in the schedule and I was accused of wanting things only when it was convenient for me. So much for fixed OR flexible schedule...

Unfortunately, it is the child who looses the most in a separation / divorce.

Is it inconvenient? Sure. Does it svck? Yes. Can we control others? no.

Rather than trying to push some change on him, how can you work with what you've got?
