I am a 23 year old female. I have become infatuated with the front desk attendant at Gold's Gym. The problem is, I cannot tell if he is flirting with me or just being friendly and doing his job. He always says hi, always smiles, asks me about my weekend, etc., but I am worried that I am reading into it too much. I would just give him my number but I:

Have no idea how old he is.

Do not know if he's single.

Do not want to have to schedule my workouts around his work schedule in the event this all goes horrible wrong.

Any advice? Do I approach him? Do I wait it out? Should I just do some squats, eat some oats, and STFU? This feels like a big deal to me because I am rarely attracted to people before knowing more about them and I am just now feeling like myself following a terrible breakup last year.

Please help.
