A TwInKlE in His Eye's

I thought I was the one to be,
But a glimmer in his eye,
Told to me,
This was all a lie,
Another is here,
Covered deep inside,
Leaving me no where,
I'll fight to hide,
I want him to be happy,
Even with another,
Inside I hurt badly,
But I still wont bother,
Because it is karma I say,
For everything I've done,
Time for me to pay,
Soon I'll be gone.
