Is he not interested or is he upset with me?

There’s a guy I’ve been talking to on and off for a few years. (My age here isn’t accurate, I’m 25 and he’s 36). We only ever kissed, never did more because I got into a relationship then he did as well. We tease each other back and forth and sometimes are pretty mean to each other and I get the vibe I went too far the other day..

We were making plans to see each other and most likely hook up and he messaged me asking if we could do it the next day instead etc. at one point he told me to “be nice” and I responded with “no, I’ll treat you however I want , you’re a fuck not a friend”. Mind you, this is how we speak to each other and I thought we were in agreement that there will be no feelings attached.

I messaged him again that night and he responded , then the next day I messaged him and I’ve been on delivered for 5 days but he watches my stories almost immediately.

Could he be upset with me?
