I am seriously attracted to him.What to do sister's?

I’m 22F and recently joined a gym. There’s this guy (29M) who works there / trains there — not really my type looks-wise, pretty average, but he’s well built, confident, and works in IT with a good salary. He started helping me with workouts, guiding me, correcting my form, and we slowly got comfortable around each other.

Over time we got closer… talking more, joking, spending extra time together. It started feeling like more than just gym friends. One day things escalated and we kissed. After that, I started taking it more seriously and asked him if he would ever introduce me to his family or if he sees this going somewhere.

That’s when he was very blunt — he said he’s already engaged and that what he feels for me is just physical attraction, nothing more. That honestly broke me. I felt stupid for getting attached and believing there was something real.

I tried to distance myself, but he kept coming back, being nice again, helping me, talking like before. And somehow I got pulled back in emotionally. Now he’s asking me out on a “date” and clearly wants things to turn physical.

I’m really conflicted. Part of me is hurt and knows this is wrong, and another part of me still feels attached because of how everything started and how he treated me initially.

I don’t know if I’m overthinking or just being naive. Has anyone been in something like this?
