You guys are probably talking about romance. Romance is magical and wonderful, no doubt. We are attracted and attached to someone. But that's not love.
Romance is a need, an impulse, a desire. It can drive one crazy. But it is all about oneself...not about the other person. When it breaks it is not always pretty. Can be nasty, in fact.
And that is my point. We are under the illusion that we love someone when all the while we are merely satisfying our own need. We justify our attractions and desires under the name of love. 'Love can't be bad, surely'!
