Guy's Behavior

What’s his deal?

I stood up from my desk and I noticed the guy I liked walking past and he was already staring at me as he walked by. I approached one of our coworkers who I work with, to get his opinion on my work. And the guy I like stopped walking mid way, turns around and stare at what I was doing. I glanced up and we made eye contact, and he asked if I needed help while smiling. I smiled back and shook my head. He continued to smile and slightly walked a bit initiating that he wants to come over. I told him that it was okay and that I didn’t need any help. Even though I wanted him to come over anyways. He didn’t listen and walked over, checking my work. We both ended up laughing awkwardly and the guy I work with even said it was weird for him to come over and that the tension was awkward lol. I don't know what this means
