When do you know if they're the one?

Right away.
Well maybe for some not right away, but you know something is different, you can't explain it but as soon as you look into their eyes and without them even uttering a single word you just *know* something is different. They are everything you could have imagined and much more. No one is perfect, but there is someone perfect for you, someone that even the things that might upset you about them, you would not change because it makes them who they are, yes they are stubborn but it goes hand in hand with their perseverance. They make you want to be a better person but they don't ask you to change. They support you 100% and even when you are wrong they don't try to change your mind and tell you that you are wrong but instead guide you to the right way. They push you to your emotional limits, you let them in the pieces of you heart that you've never let anyone else in. You trust each other. You get married not because it's the right thing to do, not because it's expected of you, not because you're at that age, but because there is no one else in this world that you want.
