Help I Have A Huge Crush On This Guy At The Gym

help! i have a huge crush on this guy at the gym and i dont know what to do. you see, i started going to the gym because i was feeling weak and with no energy, so my friend told me to sign up for like 6 months. i didn't want to lose all that money for nothing. i was about to start giving up when i saw this guy at the gym. he started talking to me and he was very interesting. at first, i thought he was not my type, but as i got to know him more, he became more interesting. now i like him but and i think i have a crush on him. so he's my motivation to go to the gym now. but i have no idea how he feels about me because sometimes, there's this other girl who talks to him a lot and she is much prettier than i am so i dont know what to do about this situation.
