Should me and my crush date?

well should i ask him out all my friends say go for it because they all think he still likes me :) because the reason i said still is because i know for defonate he liked me and yes i liked him back...but i was way to shy to ask him he still gives out lil signs like always looks at me in the corridor straight away trys to make convosations always looks around to see where i am when im off ill (my friend told me XD) gets really jealous if i talk about a guy or a guy trys to make me laugh i can tell by his face soo guys do you think i should? im still scared but im trying to pluck up my courage! hehe no harsh comments :D
