Think of creatures that are blind, but those who see know that the colors are there. Some people are blind to what love truly is.
Now imagine that a creator out there that loves us, yet we do not acknowledge that and love him. Perhaps when we all learn to see him and love him, we will learn how to love others and be loved.
Love is not what you get out of a relationship, love is what you give to it. True love is a choice, not a feeling. The feeling is just a reward for doing what our creator wants us to do. How many parents have listened to their kids scream "I hate you" when the child didn't get what they wanted? Yet the parent still chooses to love their child. They make that choice and because they make that choice, the love is eventually reciprocated again.
The world is what we make it. If we have no respect for another person's affections, we will all go out and continue hurting others.
Too many people see love as possession. It has nothing to do with that. Love should be treated more as a respect for another. An honor to them. Instead we treat people as property and we try to control them. Why not learn from them instead? Even very misguided people can have some wonderful strengths that get them through life.
Learn from love, don't try to box it up. If you do that, you will have it forever.... even if the person who inspires goes a different direction.
