So please stay in my past

I understand
Your need to switch
the roles around
And despise me for the
Fact that we didn't last
And I'll be your punching bag
If you'll stay in my past.

I understand
To want to have a
mature dialogue
Is too much to ask
and I'll be your one regret
If you'll stay in my past.

Part 2

I understand
You delude yourself,
and sleep with
different girl
Each night in order
to recover fast
And I'll let you cheapen 
If you'll stay in my past.

I understand
That we can never speak again
And your resentment towards me
Will last
And I will let you forget me
If you'll stay in my past.

Part 3

I understand
That you will one day love again
And that it's selfish of me to
want to ask
If you can only live off the
memory off me.

So please stay in my past
