Title help pretty pretty please???

The latch
All rusty and old
But strong no doubt
Keeps a very firm hold

I tug and tug
Where is the key?
I can't find it any where
I look into the depths of me

I look in my heart
And there I find
A key to the latch
That'll help us unwind

I hear a small click
The book finally opens
I read through the pages
And discover where it begins

You,
My darling sweet
Have kept many secrets
From not only me

That's why you hid it all
Under a strong lock and key
No one was to find it
Especially me

Your stories are heartbreaking
Can I help mend?
Your secrets are extraordinary
Will I still be your friend?

Your dairy
You've let me read
Tells me that
You have the most trust in me

I thank you so much
For your sharing your deepest thoughts and feelings
It must take a lot
Showing them to me

Your secrets
We share
Everything we know
Shining bright and clear

Your diary is ours
As i've now becomed enmeshed
I'm excited for all
That follows us next.
