Got a crush on my coworker but idk what to do

She’s 2 years older than me. She’s absolutely gorgeous. She might already be spoken for. Apparently, another dude I work with has been hanging out with her a ton. My copium is that he’s ten years older than her so it probably isn’t anything romantic. I have two conflicting ideas. Nothing is set in stone as I write this, so maybe there’s still a chance or I should start to get over her. I probably should’ve shot my shot sooner.
