what to do???..., when it's like this... Options

[na-nancy]

so at the school dance..
my best guyfriend....
confessed to me...
and he asked me out.
he told me he really likes me.
and i was surprised..but i knew that he liked me..for awhile..
ever since freshman year too.
and...he's a sweet guy..all i can ask for in a guy.
but here's one thing....
he's a bboy..im a bgirl...he, me, and my brothers are in a breakdancing
crew...together.
so we're a team.
it's hard because.
he's my brother's friend too.
i think i like him too, maybe even wanting to be is girlfriend.
but i'm afraid...of the relationship between him and my brothers.
it's gonna change...he and i aren't so sure either.
i don't really know what to do.
and he and i are afraid of what might happen between me n him if we break up one day and never talking again...never being friends how we are today.
he's giving me time, all the time in the world to answer him.
he says he can wait, no matter how long.
i enjoy being with him...at times.
but still..i don't know what to do.
advice?
