Start to End...just like that

I want to be mad
For what you do to me, eachday
Toying with my heart
Then letting go and walking away
You run to her
And leave me alone
Then come back at night
To talk on the phone
When I hear your voice
My heart skips a beat
And each thought of you
Makes my knees get weak
This feeling passes
And my stenght just leaves
I can't get mad
For you make me smile with ease
But I can't stay
Because with her
I'm second by the end of the day
So I leave my heart
And forget the start
Because although it was perfect
You decided the end
By not making a choice
And now it even hurts to much
To just be your friend
