Is it better to marry someone you love or someone that loves you?

This question has been killing me for a lot now… I don’t have an answer for it yet…
I felt both, loved and being loved… But both feelings were not the same by the other side. The first one loved me much more than I ever loved him… He was willing to do anything just to make me happy and be my side… He did all he could to win me, and I didn’t give him a chance… was it just because I didn’t love him back as much as he did? Although I had everything, I couldn’t go on with it because I didn’t have that much love for him… He was more a friend than a loved one…

Then I met this other person, whom I loved more than I loved anyone in the whole world… I was willing to give up anything just to make him happy and be by his side… But he never loved me that much… I sometimes wonder whether he loved me in the first place… I believe I was more of a friend to him, or a younger sister, or maybe even a younger "guy" friend… He cared a lot to be honest, but love, I don’t know if he ever loved me as much as I did. With him, I did so many things that I never thought I would do… I crossed all the limits that I set for myself and I changed a lot hoping that he would love me more, or love me at all… But he was never satisfied and never happy with me… And that was when I left and decided that he doesn’t want to be with me…

Was I wrong? Was I supposed to cling to the one who loved me better than the one I loved? Or is it a normal phase that any person should pass through before finally finding "the one"? I have no clue…

What bothers me is that I am still clinging to the one that doesn’t love me… And whenever I give myself the hope by feeling like he loves me, I realize that he doesn’t and that it is just me trying so hard to find what I am looking for… Will he ever feel the same? Did he ever feel the way I felt for him? I don’t think so… And I don’t think he ever will… But, does that mean I should go look for someone who loves me better than running after someone who doesn’t have anything for me?

He keeps giving me hope and taking it away from me… He keeps making me over the moon then sending me back to earth down in the deepest of holes… Today, he told me "you deserve someone better than me"… A while earlier, he told me that he will marry me by the end of this year… I have no clue what to do… And I don’t know how to deal with this heart of mine…

I am starting to hate him… I am starting to get tired of waiting and hoping… I am fed up and sick of his presence and absence… He being there and not really being there… I am soooooo tired of this… I want to get to know where I stand… I really wish I would get out of this whole world…to find a cure to how I feel… and to get rid of your spell…
