I'm in love with him but he sees me only as a friend. What should I do?
if you really love him, firstly tell about your feeling upon him that how much you love him. just try to get to know what his reaction after knowing about feeling & give him time to think about it for decision because love is the thing you can't force to do it, so my suggestion is to give a chance to give love. by the way love is form of different forms:
So if he seem as friend. So you will make friend you him and do all of the thing those he like and will try to understand to him you are in love with him. You will try again and over again. He accept you as love.
It is all allready happen with me and she was accept me after 18 months. So please try.
