I can't be your friend anymore

This might come as quite a shock
But I've given it a lot of thought
This thing that's come between us can't be ignored
I've taken all I can
This is where it's gotta end
Cause I can't be your friend anymore
And I can't be accused
Of not bein' there for you
How many nights have you shown up at my door
I hope you understand
That this wasn't in my plans
But I can't be your friend anymore
