Feelings for someone else

I started a new job and there’s a guy who has caught my eye. We are always finding opportunities to look at each other. When we look at each other, I get an overwhelming feeling. It’s like I can’t look away or stop myself from looking at him. My heart races and I am unbelievably nervous. I finally worked up the nerve to talk to him. It wasn’t a long conversation because we both were busy. I just asked him what his name was. He told me and I responded by saying it was a nice name. He smiled and asked what my name was. When I told him my name he smiled and said the same thing I said about liking my name. Then before he walked away he said nice meeting you. Anyway, it was a short conversation. After our conversation he kept looking at me as if he wanted to say more to me. This might sound crazy, but I feel like we were meant to meet each other. I feel like we have a connection even though not many words were said between us. I feel like he might be the guy I’ve been waiting for. It’s crazy to even think I’ve found the one when I don’t even know him. And also I have a boyfriend who I love, but I am developing feelings for this new guy and I don’t understand it. I don’t know if it’s just a crush or something more. I need some advice. Is it just a crush?
