First and Last

You were my first love,
My first heartbreak.
I wish I could forget
The first time I ever saw you,
And make it the last.
How could you,
The reason of my happiness,
Make me cry so much.
You don't know it,
You don't know what you're doing to me.
You don't know my feelings.
Which makes it worse.
How could you not see ?
How could you not feel ?
All i can do,
Is love you at my own expense.
