Am I being unreasonable with him?

My boyfriend doesn’t have a car so I took us out to dinner and I wanted to go to the gym with him.

The whole time he complained about the food and how it used to be better but now it’s shitty..

We go to the gym and I wanted to work out with him but he ditched me. I have huge amounts of anxiety at the gym and it’s my first time going and he completely left me.

I feel kinda used that I was his ride to the gym and he was not appreciative of the dinner I bought us.

Would you be upset? Am I being too sensitive?
