Just need some clarifications?

Ok so i started working as a cashier. And i had a supervisor who helped me get the hang of it. You know the first days of work is scary and he was totally supportive and made things seem not so bad. And we started small tlk nothing big. We were working and i was overwhelmed. He winked at me telling me that hell help me out. And it got me. I turned around and laughed. In my head i was like omg. Then i started to like him. We tlked a little but more when i was done with my shift. We just tlked about iphones cuz i had one n he said he repairs them. He was just telling me about what he repairs and thats it. He found out that i had one cuz i was bymyself at lunch using it. I have a boyfriend of 4 years. But i guess i have a crush on my supervisor. I'm 20 and hes 28. He looks young tho. And everytime i see him i get nervous. I don't want to like him. Its not that big of a deal cuz i don't want to be with him. But I just keep my ddistance. You think he likes me? How can i aviod him?

There's a phrase… "don't *** where you eat"---think about that for a sec.

If this job is his career, then you should avoid flirting with him because it could cost him his job. Maybe you are cute and he was being helpful coz you are new. But just because you suddenly have a crush on him, it does not mean he likes you too.

Keep everything on a professional level because both your jobs could be in jepoardy as upper management does not like this sort of thing and other co-workers might get mad at you if they think he's giving you special treatment and start to cause trouble for you. You are new here---why risk your job and reputation?
