Gym crush on a personal trainer

I 26F had seen a personal trainer from far a few times around the gym, he was always busy with clients so not sure if he ever noticed me before. Last week i decided to use my gym service of free 15 mins session with a PT which i requested with him.

He was absolutely amazing. We spent 40 mins together instead of 15 mins. He did ask questions like how old I am and what I do, he also talked about himself a lot and his background. I really liked him. He is very my type. He told me multiple times to updated him on my progress and reach out if I ever needed anything else. We already have each others whatsapp where we organised the session, so i did say thank you afterwards and he again said to update him how things go.

Am i being too delusional or could this mean he liked me? It is his job to be friendly but also since he is employed there maybe he isnt allowed to cross boundaries..? How would I know 🥺
