Love is subjective.
It's a chemical reaction that is linked primarily to the species need to reproduce, though not always directly. You love people who are not related to you, without a sexual component, because it activates certain other pleasure centers of your brain. In the end, it is a pursuit of pleasure. It improves the quality of life in overall terms for some, while it decreases it for others. So a very subjective phenomenon. For me, it increases the excitement in my life, I'm much less bored and it makes me more open to other normal situations which I otherwise avoid. All this works fine until the novelty wears off and then I'm back to being bored with life again.
