How do you?

How do you love the person who makes you so mad that you just want to leave?
And how do you love the person who makes you cry every night and you cant even stop?
Tell me how can you take another day with the person you love when they just hurt you in every way?
How do you smile with that special someone when all they do is make you sad?
How do you love the person you love when you are breaking apart?
How do you love the person you love when they don't even love you?
How do you know it's love when nothing is even there?
Just how do you love the person who sits there and makes you cry and he never lets you be happy?
