Simply Unrequited, Happily Unloved

I hate that I love you
Wait, scratch that
I hate that my loving you makes you unhappy
How it causes you pain
Because all I wish to see is you happy
Your laugh
Your smile
These are what makes me love you more
Your happiness is mine
Your pain is mine too
So just ignore my feelings and be happy
I know you like me too
But that doesn't matter
Your heart belongs to him
And while that causes me pain
Seeing you with him instead of me
It all doesn't matter
Because he makes you happy(sorta)
