Is my friendship onesided?

I love my friend dearly...shes wonderful. The thing is that everytime I wanna do something with her...i have to ask and/or invite her. And its not like she ignores me...shes always agrees and finds time...if she cant on that certain day...she'll always propose another time to hang. She's also a really busy person, she takes like 3 extra cles outside of high school since she's graduating early. She doesnt ignore me..she always listens and we love hanging out with each other and we're never bored together. However she never inititates anything with mer...and it not just me it with everybody...she doesnt really call anybody unless someone invites her to do something. I'm probably just taking it too seriously or taking it the wrong way...but do you think that this friendship is onesided?
