No one on this planet was created for you. They all exist for themselves. Love is a matter of choice.
No one will fit you perfectly, and perhaps it's worth stopping to raise everyone in the belief that somewhere there is that one person "created for you," because it's not true. No one is meant for you, except yourself. Other people also belong to themselves.
If you want things to work out with someone, it implies hard work, empathy, mutual understanding, and the right to choose.
