who was Bert?

Bert appears in my dreams almost every night, drunk and screaming and having a bite...
I’m so full with faded frustration!?!?!?
Why the fucked up liquor situation? 

She came home with so much ignorance..
While Bert was bathing in drunken innocence. 
 
A pack off brewskis on my head so Bert could shout, I’m sure the Hootch is what tuned him out! 
From anger to smile is where it went.
A Second hand child is how I felt.

Do you blame me for your demise?
You appear in my dreams with so much despise, Like when you were alive, never a kind word or an achievement you could recognize. 

You shall honor him is what he said.
I never laid a hand on you but I wanted so bad.  

He is she that made it hurt! 
Now ask yourself...

Who was Bert?
