So I started up at a new job a couple months ago and I've developed a crush on one of the guys that works at store next door. I see him all the time as he's always buying drinks and snacks at the Café I work at. This one day he came by more times than usual, at first by himself, then with a co-worker, then with another co-worker who I get along with. He seemed to let his co-workers do all the talking as if they were his wing men or something and at one point he made a dirty joke, judging by their reaction because I didn't get it and they definitely noticed but we just laughed it off. The next day I decided not to break eye-contact when our eyes met and smiled at him while maintaining eye-contact, he smiled back and walked up to the counter, asked for what he wanted, paid, and stood around but I couldn't start up a conversation because I had to tend to the other customers. Later that afternoon, I saw him again, we made eye contact, he started walking directly towards me with a smile on his face then just stopped in his tracks around and left? Since then he doesn't really come by much and if he does it's super quick and just stays silent when I try to start up some small talk (i.e. ask him how he's doing, etc.). I've seen him fixing his hair and making sure he looks fine before walking into the Café and although he hasn't said he is, I definitely know he's gay. Seeing as how I'm not very experienced with flirting and letting a guys know I'm into them, I make this post seeking any tips and tricks anyone might have that could help me out with my little dilemma. Thank you for helping a hopeless gay in need!
