Triangle Love Story
I love a girl, she is my friend's sister, who moved to UK for job purpose. After she left her sister became close to me. So close that I even took her outside on my bike and helped her every time, when needed me. Becoming close to her made me fall in love with her and there was not yet a name given to our relationship, whether friend, best friends, lover or siblings (I don't want the last one or the first one).
The first time I told her that I loved her by expressing myself in indirect ways, she noticed and rejected my words and she also indirectly told me that she was committed to other guy. We did not chat for a few months then I rang up and told her I was sorry again we became close. It was the same as before: me helping her, but this time we grew even closer, but suddenly, she stopped talking to me.
Now I am very much upset and she is still not talking to me. But I love her very much, which she might know but is acting as if she doesn't. I want her in my life forever but times I also feel like that guy, who finds himself to be lucky getting this kind of girl.
How can I make her realize that I love her very much, more than the guy with whom she is committed. I can take care of her and if she goes away from my life, it will kill me.
Please suggest something that I can do to be closer to her and win her love.
