Here's the thing.
There are seven billion people on the planet. Out of those seven billion, you'll meet tens of thousands. Out of those tens of thousands, you'll maintain real relationships with only one or two hundred. Out of those one or two hundred, only a handful are really worth knowing. Only a handful will know you intimately.
So when you find someone that helps you be the best possible version of yourself, someone who makes you laugh and feel loved and like you can do anything, someone who isn't nuts and doesn't want to do anything with your emotions but nurture and protect them, you hang on to that person, and you don't treat them like shit.
It's not always easy, and the timing is never perfect. But you make it work.
You respect them.
You listen to and support them—through everything.
You don't play games.
You say what you mean, and you mean what you say.
You give them what they need.
You don't give up.
You do whatever it takes.
You make it work.
A person unwilling to adhere to each of these values is not worth having in your life. Look to the next better thing.
The world is full of people willing to screw you over, on purpose or by accident. People are generally good, but that doesn't mean they aren't looking out for themselves first. I don't blame them. You have to take care of yourself before you can take care of someone else.
That's why unconditional love is so rare. For two people to be so confident in who they are—as a team and as individuals—that they are each capable of putting the other person first regardless of conditions or convenience is so rare, it can take a lifetime to find.
Those odds are the stuff miracles are made of.
