What is love actually???

Sometimes i really don't know what love is. I thought that i have give?n him all that i have. I am trying my best to make him happy. But why am i not feeling happy? What have happen? Don't i love him anymore? Have our love change? I really don't know what love actually is anymore. Why didn't i feel his love for me anymore? What am i to him? I really don't know what am i to him.

Sometimes i think by myself what does the future holds for me. Is he really the one that i am going to spend my whole life with. I am starting to have that kind of fear again. The fear of loosing him, the anger that i have when he spend more time with his friends than me. the jealousy that he have more things to talk to other people than me. Does he really love me? I really wanted to ask him what does he plan for the future. But to me i think that he is not those kind of people that plan for his future.
