Being Jewish doesn't corner the market on guilt. We Catholics have a lot of that too!
Did I at least make you smile?
Your AB has in effect thrown his own guilt on to your side of the court, and you picked it up.
It's his guilt over his addictions (alcohol and cocaine), his guilt over his life choices, and I highly suggest you throw that guilt right back over on his side of the court where it belongs.
You are standing up for what is right in your life, and I'm proud of you.
