Wasted Opportunity

I just can't help but look at her everytime I see an opportunity  Has my affection with her turned to an obsession already? I want to look at her everytime, I want to be with her all the time -- sadly it can't happen anymore. I want to tell her I still love her. I want to tell her I'll wait for her. I want to tell her just how much she means to me, but I'm afraid that if I tell her she'll put up that barrier again. If only I didn't waste the opportunity she gave me the first time, I really wouldn't be facing this problem.  But what's done is done. Much as I want to be with her, I can't. Plus, with all the eyes at us everytime I get close to her, I just  can't help but move away. I wish there's something else I can do to put the things back the way they used to be.
