Non-love Typical of most personal relationships and casual interactions.

"Acquaintance A person whom we know well enough to borrow from, but not well enough to lend to." - Ambrose Bierce

Friendship A close bond without intense passion or long-term commitment.

"One of the most beautiful qualities of true friendship is to understand and to be understood." - Lucius Annaeus Seneca

Infatuated love Lacking intimacy or commitment, the infatuation may disappear suddenly.

"There's a big difference between falling in love and being in love. There's a big difference between infatuation and falling in love." - Phil McGraw

Empty love Characterized by commitment without intimacy or passion. E.g. an arranged marriage.

"Thanks to arranged marriages: There are countless women who have never been their husband's girlfriend." - Mokokoma Mokhonoana

Romantic love An intimate and passionate bond without commitment.

"In real love you want the other person's good. In romantic love, you want the other person." - Margaret Chase Smith

Companionate love An intimate, non-passionate love stronger than friendship because of the element of long-term commitment.

"As you get older, you realize it's work. It's that fine line between love and companionship. But passionate love? I'd love to know how to make that last." - Tracey Ullman

Foolish love Exemplified by a whirlwind courtship and marriage.

"First love is only a little foolishness and a lot of curiosity." - George Bernard Shaw

Consummate love The complete form of love, epitomized by "the perfect couple."

"I love my husband very much. I knew it was real true love because I felt like I could be myself around that person. Your true, true innermost authentic self, the stuff you don't let anyone else see, if you can be that way with that person, I think that that's real love." - Idina Menzel

Unrequited love Love that is not returned.

"People do incredible things for love, particularly for unrequited love." - Daniel Radcliffe
