My mistake

Our friendship was strong
every thing was going right
then i did something wrong
and now were not so tight

i did the worst thing
a best friend could ever do
it was only a fling but ended up hurting you

he was your guy
and we went behind your back
Ive caused you to cry
and wish i could take it back

I'm the one to blame
I'm the one who lied
i feel really lame
and trust me i have cried

now this is me
trying to make
you understand
I'm sorry i made a mistake
