Are you seriously waiting
for her to tell you that she likes you too?
I can tell you, you are gonna wait long long for that to happen.
The thoughts anc concerns going through your mind right now could
be exactly what she is having in her very own mind. So if none of
you going to make a step forward, who's going to do it for
you?
In fact, it would take more and greater courage for a girl to come
up and tell you that she likes you. So for you as a guy, you must
take the first step forward. You want to love her legally, but you
do not have the courage to declare it...how sad it is... 
If you are sure that she's the one you want right now, go for it
and seized the opportunity before it is too late. What have you got
to lose anyway? You only lived once remember??? At the most, you
will be terribly embarressed when she rejects you...but at the end
of your forsaken life, nobody will ever remembers what happened to
you and nobody will even remember you as a person. So if you can
meet that special someone and fall in love with her, have a great
relationship and future...at least there is one person in this
world who will miss you when you are gone eventually.
If she likes you, she will still like you even if you gave her the
lamest crappiest excuse in the world to see her again. If she
doesn't, she wouldn't blink an eyelid even if you hand-carved a
statue of her and gave it to her.
An average person waits for good things to come to them, but an
extraordinary person create good things for themselves and for the
people around them. 
Well, eventually it is all up to you to make up your mind and take
some actions. Afterall, you are the one with the balls and I hope
that those sacs are still attached to you. (*Joking!!!)
Good luck.
