I like a boy and Im in 5th grade my friend told me he likes me but I don't know how to ask him out?

well its simple,just walk up to him and start talking to him,and then add in hey,by the way,do you have a girlfriend?and he'll say no,so,then,you say,oh,what coincident!slip in well,wanna change that for me?

then the asking is over(im in the 5th to)
Good luck!
