What is love?

The eternal question. I have felt many types of love. I have felt a recent romantic love. A love without commitment or risk. Now I am heading towards love with committment and it scares me. I will be putting myself at risk. But I am driving the direction. Why am I heading for this when it is so scary? Does it need to be scary? Yes otherwise you are not really living. Too put my heart in the hands of another. I said I will not do this. I can give love without giving my heart? To give my heart would make me vunerable.
