How can I tell if a Virgo man likes me?

I've known this guy for a few months, and I've taken a great interest into him. I'm a Scorpio-Sagittarius Cusp and my mom is a Virgo. My friends tell me that he does like me because we always sit by each other(he sometimes moves around like he's nervous sitting next to me), he talks to me a lot, and the way he looks at me i guess. We have things in common like music, drums, etc. He even invited me to his band performance at school. Sometimes I'll see him around at school during passing periods but kind of act like he didn't see me so maybe that means that he's sort of shy about it. But I'm not the best to really tell if someone likes me or not. I do realize that Virgos take time to figure out if they like someone or not, and I'm same way. But I'm still unsure, please help?
