What do you think of love IN GENERAL? Is it more bad or good? Would you be happier in a world where love doesn't exist?

"love" as an emotional attachment, affection, desire, longing, you name it, between two (or more?) adult people. Love for children, love for things, pets and hobbies doesn't count. Friendship also doesn't count. Further definition is yours.

Inspired by the fact that there are many different opinions on love, ranging from "it's the best thing of our live, we live to love" to "the love is blind, painful and meaningless".
