Why is the first love is the hardest?

Yes, I am completely madly attached to him. I do not know why I have been locked in this cage for two years and I am still attached to him.
When I feel feelings for another guy, I still care for him and I feel very sad that I will leave him or he forget me one a day and I feel as if he is doing something to me make me very attached to him! Why am I locked in a cage and my heart is broken, and when I tries to go out, my heart is broken and I feel very sad.. very sad
