Bestfriend with my boyfriend

With everything you've done
And everything you've said
It looks like you had fun
Just messing with my head.
Hopefully y'all enjoyed it
All the time y'all spent alone
I'm tired of the bull sh**
And its time for me to move on.
The first time I heard that y'all kissed
That should have been the end
But I gave you the benefit of the doubt
Because you were my best friend.
I'll never be able to get over this
These wounds will never mend
And it all hurts the most
Because it was my best friend and my boyfriend.
