SHY GUYS- Should I give him my #? Are these good enough signs that I should proceed?

[Hiiiii]

-He's a senior & I'm a junior, we have no classes but we're both in drama club. I haven't been to drama club in a month b/c my parents won't let me, so I couldn't get on crew (I'm doing it for the spring play though), however I'm in pit orchestra which is going to start rehearsing at the same time as a crew works- for like 4 hrs- so I can talk to him before and after
-I've had a few conversations about music on twitter direct message & also tweets. He seems really engaged and talks more than he does to me in person, but then he always stops replying (honestly, I think he just forgets to check or doesn't see that he has a message )
-I only see him a few minutes a day, in a small band/orchestra locker room with nobody else there. When we talk in person, usually it's just reallyyyy small talk. We talk about other stuff too but there's not much to say in like 3 minutes so it ends (I have lunch & he has to go to band). He's known to be veryyy shy, but a lot of girls like him for his looks. I'm trying to actually get to know him though. He says hey and smiles now almost every time he sees me.
-The first time we talked, he blushed a LOT. I thought I was imagining. He has full-faced blushed while talking to me alone like 3-4 times so I know it's not just me.
-We've talked about a music website a couple times & I told him I got an account (he has one too). Recently, he posted the link to it on his bio and changed that profile picture from nothing to like the best picture of him. I only know like one other person who uses that website. Could he be trying to get me to add him? I haven't yet.
-I haven't talked to him for about a week and he hasn't started anything. But he's a quiet/shy guy so even if he did like me, I'm thinking he wouldn't start it (which is frustrating to me).
-I want to give him my # but idk if he'd even text me due to his nature or if he even likes me

A couple weeks ago I was at set shop for drama club after school (but my parents didn't know). Some guy was signing in. I asked if there was set shop since there was nobody else there, he said "yeah I'm just helping *insert name*" & the guy I like came out from where he was working, I waved to him, then he stood next to that other guy. When the other guy had to leave, the guy I like started talking to me. After that, I came back and asked if they need help, the guy I like said "I don't know...(thinking)" and the other guy said "No. This is really just a two-man job over here" and I said "Two MAN job?" & the guy I like looked at him, smiled, and chuckled like he was surprised since never saw that side of me.

Look, it seems like you have a strong enough bond to give him your number. Take a stab at it, if he says no, remember that he's shy and try and do it in private, not by his mates.
