I didn't, You did.

I didn't leave you

I never wanted to

But you left

When you said that you were tired

Tired of all the drama

I didn't leave, you left

Ran away and found comfort in someone else

I kept running after you

But sometimes I get tired too

So I stopped

Stopped running and got accused

Accused of infidelity

I laughed inside and stepped aside

I realised you're not my cup of tea

You told me I wasn't good enough

But baby I know that I'm the best

Your mind may think that I'm a bluff

But heart sure knows that I ain't like the rest
