What does it mean when he says i’m not looking for anything and i’m still working on myself?

I met, my trainer on a dating app and boom now he’s my trainer. I waited about a month or so in to shoot my shot and he said he’s not looking for anything right now. Which I thought was confusing since he liked me first on the dating app and I also know he hasn’t been doing the best with his mental state and he had some family issues going on. Everyone is telling me to stop talking to him since he doesn’t seem professional anymore with our relationship and that he clearly doesn’t know what he wants
