Analysis of Pretend?

How could I pretend it never happened?
Pretend we never met,
pretend you’ve never held me in your arms.
or that I never laid my eyes on yours and surrendered to their charms.

It sounds so simple to pretend.
Surely you must think it would be easy for me,
to live through such a dense lie,
but I am haunted when I rest
and once I rise by the fact that we never Actually said goodbye.

Once my pretending is over am I to just forget?
Forget our memories,
forget our laughs,
our adventures and our ridiculous inside jokes.
But to think one day we may forget each other’s voices is what really hurts me most.

And upon forgetting will our world not crumble?!
If you and I
both remove the same memory from our heads,
-for it to never be remembered again.
Will we continue to live our lives satisfied with the presence of another in our beds.(?)

They tell me life goes on,
And, perhaps it does.
But,
Perhaps it doesn’t,
for how am I to breathe air which you haven’t exhaled.
How am I to read harmonic love stories,
knowing that our love hadn’t prevailed.

How am I to ever stop loving you.
Missing you, wanting you, hating you,
wishing you had died.
For perhaps if you had left this world,
Missing you would be much more reasonable,
with there being no chance of you again being by my side.

I wish it was so easy to simply Pretend.
