I dont know if i shoould ask him our or not!?

plez help. Its clear he likes me from previous questions and my mates say so! He holds doors open 4 me, laughs with me 4 no reson about nothing! He makes me laugh! He shows off how bendy he is 2 me! winks at me! Shows off genraly! Smiles at me! Supports me! But he goes 2 my dance scol (he aint gay) and hes like 10 or 11 months younger than me! Im 13 hes 12! Anywho... Im frightened if i ask him out he will say no. Or keep away from me if i ask him. Or if he ses yes he would act normal and not treat me speshial like smile at me and stuff above. Coz i would like 2 hold hands with him and stuff but 4 sum reson i think he would just b normal and not do anything! WAT SHOULD I DO?? P.S. I hav neva asked a boy out in my life my friends did it or he asked me!! Help plez ~X~ <3
