We're breaking up!

We're breaking up!
For quite a time I feel like hobbling
And my whole life is such a limp!
And though I know that you're a reason
I can't get over that damn crimp.
 
Boldly surmised that our story
Came to an end because of me!
With that egregious accusation
I will profoundly disagree.
 
You are the one who's always whining,
You say "Why won't you just let go?"
But I feel sick of self-confining:
You were the best - not any more.
