Advice needed (potentially awkward situation) ?

I've (20 something female) recently started with a male personal trainer at local gym. Only had one session so far but he seems genuinely nice and really knows what he's doing, I like him! Now I'm also on and off dating apps atm and only noticed yesterday that he liked my profile (I've tinder gold) but seeing as I haven't been using tinder the past week I don't know when he swiped right on me... I also had my account on pause for the last 3-4 days maybe. I'm not sure what I should do here, as perhaps he swiped right on me before our first session and didn't know who I was. He was really friendly and chatty during my session in the gym, but I imagine all PTs are like this as it's good business. We were supposed to have one again this evening but he's cancelled and rescheduled for tomorrow. Really not sure what to do but I do find him attractive and he is also moving abroad soon (in a few weeks time). Any advice welcome, pls be nice!

So… I liked him back on Tinder but no match made! He may have deleted his account and now I feel terrible
