HOW DO YOU TALK TO BOYS???

I'm writing on here because I don't have any place to vent .
This morning I took the same bus as this boy that I had a crush for the last 3 years, we used to be classmates 2 years ago. We didn't talk much, but this is my last year where i can see him, and I wanted like re-establish whatever we had before, and even hiped that we became friends. So seeing him today taking the same bus as me really encourage to go talking to him. But the moment we get off the bus, I went to him and i was like "hi" but he seemed a little surprised so I asked awkwardly if he remembers me, and he answered awkwardly smiling "maybe?", That shit felt like slap i wanted to cry, I don't spend a minute without thinking of him, and he was like maybe, like no would be much better. So i add if he take the bus everyday, because I wanted to ask if i can take it with him, but he answered "no, i go walking" and i know he was lying because he lives so far, and the only available bus at the time is this.
Like thinking about it i think he just didn't want talk to me, but like how can you talk to guys?
