I'm in the wrong?

This heart still hurts when it beats
These eyes still sees that moment
These ears still hears your stupid explanations
This hand still wants to get a piece of her.

"Baby I'm going out." she said
"Where are you going?" he said
The next moment my hand was trembling
The heart I knew cease to exist.

I still feel my heart breaking
And you will never know the pain
"My mind wasn't thinking straight dear"
"I promise I'll change"

You blamed me all these time
Because I couldn't forget your simple crime
You broke my trust
And now I'm the mastermind?
