How do you know it's right?

How do you know it's right? When the one your with is your one and only How can you tell it's true? Can he really be faithful on you? When you've felt the hurt and been the lonely All you can do is fright and worry But one day it all makes sense Everything he does is to make you happy To work towards a future you can share together When you look into his eyes and feel the love flow through He won't make a decision without asking you You choose a path, and he chooses his We'll meet in the middle and stick it through He'll love you, and no one else The promises, the compliments, the pure deep love Will never stop and never stop coming Love that could never be broken You can feel it in your soul That's when you know it's right
