It's me or her

As i sit here alone
Thinking about the past
Wishing i could change it
It all happened so fast

I never meant to lose you
You know you are my life
I'd give anything to hear it again
When you asked me to be your wife

I cannot do this anymore
This is way to much to bear
I have to hide the pain inside
I don't think it's fair

I wish you wouldn't do this
Your the love of my life
And you don't even realize
I cry over you every night

Why are you with her
When you say you still love me
Either leave her behind
Or forever lose me
