unsure if he is still interested?

I started dating a guy about 2 months ago and he asked me out a week after we met. We got really close very quickly after we met but then he had some family and health problems going on so he was distracted so we didn’t really get to see each other, which was understandable. Now it’s been about a month since we have seen each other outside the gym we both go to and I’m confused on whether he is still interested. He sends a lot of mixed messages, like sometimes he acts really happy to see me and initiates conversation but then other days he doesn’t really acknowledge me. I’m not sure if he knows that I’m still interested or not but in the beginning he was so forward that I feel like he would’ve just asked me out again by now. I am thinking that I just have to either take a hint or buck up and tell him I still have feelings and need to know if he does too but I’m unsure of how to go about this. I want to ask him is he still feels a connection but am scared to and unsure of how to do it without being awkward or coming off as desperate. Help please!
