Shit test, how should I have responded?

The setup, our teacher told our kid he's not allowed to bring fig newtons to school because she classifies them as a cookie. It's a private school, whatever. Doesn't matter.

I tell her I'll clarify with the teacher at pickup today. They were 5 minutes late releasing the kids, and we already had to be on the road to pick his mother up from her job, also had to stand in line to pick up something from a school fundraiser. Time was of the essence and this is all happening on my lunch break.

I pick her up , we're driving a bit and she asks if I asked the teacher, I say "no." She calls me a wuss. Playfully, which she thinks makes it funny, but I know better. I give a quick chuckle and tell her to just watch it. (I wish I kept my mouth shut, but this whole red pill stuff is very new to me, I don't want to go too hard too fast, as she's already accused me of texting with some imaginary woman she thinks I've been working out to impress. I've been working out because I've decided I'm not the piece of shit society wants me to think I am.)

We get home and she's bringing me drinks, asking me if I'm okay. I told her I'm excellent and thanks for the drink. I'm back at work and not really sure where to go from here. The only changes I've really made in my day to day so far are working out pushups (consistently hitting 40) some yoga, jumping rope like a madman, and eating considerably better.

Her calling me a wuss has always been a laughable offense, nothing I would ever have gotten sore about, but now that I know the biology underneath what she said, that shit ain't going to fly right off me anymore. She then, when we get home tries to show me this new fireplace thing she wants for the living room.
