I think that love has to be the most painful emotion around.....you never know if someone else truly loves you, or just says that they do, or they DON'T return your feelings and they reject you......I remember in a song the lyrics were talking about how some people just lose hope and settle for second best, then wake up one morning when there's nothing left to say.
Which sadly, I think is probably true.
Plus, how do you KNOW if what you're feeling is love, or just strong feelings of affection and protectiveness?
