This is completely true. However, believe it or not, that's not a reason to avoid relationships. "Love" is one of the most used words in the English language, and yet it has no meaning. Everybody who says it means something different by it, and even the same people mean something different by it in different situations. Since you're aware of the myth of "love," you're already a step closer to happiness than most people who keep chasing something that doesn't exist.

So just find a relationship that makes you happy more often than it makes you unhappy, and then whatever it is you feel in that relationship, call that feeling "love." That's all anybody else does whether or not they want to admit it.
