Sould i ask this guy out on valentines day ??????

[Sylver]

so this guy is a peer tutor in my science class. im in grade ten and hes in his senior year.
hes the nicest guy ive ever met. i talkedto him a few times on facebook like two monthes ago. but we dont really talk much in person. i seem like a quite girl to him.
he seems to like me tho i mean the way he looks at me and everything.
but i dont know how to make a first move plus not sure if hes taken or not.

what should i do guys? should i come up to him and ask him out? would it seem slutty?

i really need your advice! thank you so much!
