I'm living proof of that.
When I met my wife I had good intentions. When I stayed in a marriage that doesn't work (to put it lightly) I had good intentions.
But then she came to work for me.
She was supposed to just a desire I would never fulfil.
I am a married man.
A father,
and she is too young.
But then, my wife crossed the line, and she came offering something I couldn't say no to, and all my good intentions went right where I was going.
To hell.
