Need help please

So I have been trying my best to go NC since my W moved out only speaking when we have to about my daughter.
I feel like she is trying to make me angry or hate her. Everything I have done I have controlled myself and been polite but only having contact when needed and ending contact first not holding on or pursuing.

I believe I am giving a very good impression that I am fine without her and she really doesn't like it.

Is this something normal that is to be expected? Is there anything I should be doing differently? It's like the more I show that I am ok and doing fine the colder she is getting.

At the beginning when she moved out she was apologetic and always saying how sorry she was because I was visibly upset but now I appear as if I am doing fine on my own it's like it has made her very angry and she's trying to make me hate her or have a fight but I just keep in control and be polite.
