The One

How do you know that person is your one? 

The one who you should end up being together. 

The one that will be by your side no matter what happen. 

The one that will accept all your flaws. 

It breaks my heart when anyone asked me; "are you sure he's the one?" and I don't have the answer. 

Or actually that is the sign that he's the one? Because I accept him with no reason?

Oh please, help me!
