I love my boyfriend but I’ve developed a crush on our coworker/ his friend

I wouldn’t cheat first of all just to start off with so that’s not a problem but idk if it’s just me that every time he’s near I just wanna Hug him or something. During work I treat him like I treat my boyfriend. I walk pass by them about 40 times during shift and everything I either poke them or tickle them and ugh it’s difficult I know I don’t like him like that but it’s like I want his attention 😪
