Double betrayal

You know nothing about marriage,
Or the meaning of a friend,
Your integrity does not exist,
You are weak so you pretend,
You'll never know what it's like,
Men have only seen your skin,
For if they saw your insides,
They'd run as quick as wind,
I know you think you got him,
Your satisfaction shows,
You never looked me in the eye,
And that is how I know,
You did take away from me,
Not just my husband's eyes,
But a friendship that I thought was true,
You crushed me with your lies,
I feel sorry for your marriage though,
It was not and won't be real,
You're not faithful or devoted,
Your heart is cold as steel,
My heart is broken into pieces,
But it could be worse,
I could be ugly inside like you,
What a dreaded curse,
So keep on smiling,
Say you're fine,
We all know the truth,
You have no depth to your soul,
One day you'll lose your youth,
And all your superficial parts,
That you think life's about,
Will one day melt away,
And you will begin to doubt,
Your old soul will start to ache,
You will be alone,
You'll wonder where your true friends are,
Because fake is all you've known
