I Thought

I thought I meant something to you,
I thought we would be together always,
I thought we loved each other,
But now...
You have fallen for her,
And I don't see why I should care,
Because we have moved on,
But you have someone to love and love you back,
But I'm here alone with no one at all
Feeling like my heart will never mend,
Even thought it's been over a month,
I sit here wishing that I hadn't made such a mistake,
And lost everything I loved,
Just...like...that...
