With addicts the choice to use or not use is ultimately theirs. They can try and blame their addiction and substance abuse on others but the problem lies with-in the user.
Affairs...we are talking about affairs in the context of a marital or otherwise committed relationship. It this case both partners played a role in the demise of the relationship. This in no way excuses the behavior of the unfaithful party but it does mean when they point the finger the other direction there may be some truth in it.
What I am saying is and what I believe Wonka is alluding to is right now is not the time to focus on any part of her stuff but rather focus on yours. If you want to liken this to addiction recovery there is a saying we repeat often. We seek to reach people through attraction not by promotion.
You can intervene and try to get her to see the destructiveness of her behavior meanwhile all see may be able to see is the destructiveness of yours in her reality.
Love you man. Praying for you.
