Momentary hate and the fall out of love

What I feel now, might not last. Hate is closer to love than we think. Sometimes I can't get over the fact that my hatred comes in such a strong concentrate, that whenever it bursts in my system I believe that I'm not actually capable of love. But when I calm down, however, I feel the warmth of love expanding through every inch of my body, not a spot untouched.
But this push & pull between love and hate comes from the people that matter to me. Whenever someone I just met or that I simply find unimportant... Whatever fills my body is nothing. No emotion. But it is even harder when the subject of such emptiness used to be the cause of the most passionate love or the utter intense hatred. When you fall out of love & realize that those feeling won't come back... you suffer in silence, temporarily, till you are truly empty.
