So I’m trying to figure out if it worth me trying to make a move on this guy that might be interested in me but I’m scared of being wrong and getting hurt

So stories is this guy I work with that I thought was hot but I didn’t pay much attention to him and I move to the morning shift and I don’t know if he was be nice or it’s something else but I was on my phone just standing there texting and I like can feel like he watching me then I walk passed him and said to me that he likes having me here in the morning I smile at him I believe he did the same another day I was talking to another coworker and he was there with someone else I felt the same thing that he was looking at me again the other time I noticed him looking at me then looks away looks back he did it like 3 times also weird thing asked him for help with a person who need help I see him later tell him thank u he say no problem then laugh for some reason I’m like what the fuck might have been nervous also We make a lot of eye contact with each I have seen him looking at me a lot of times
