My biggest mistake

Are you the person who you say you are?
Are you the person whom i was fighting for?
After what i've heard, i don't know you anymore.
After what i've heard, i'm walking out the door.

You say you love me, but are you sure?
You say you love me, but your hearts not pure.
You say you miss me, but i don't believe you.
you say you think of me, but that's not true.

You gave me a kiss, but it was meaningless
I know you love someone else, but you never confess
You gave me your heart, but it is fake.
Falling in love with you is my biggest mistake.
