Am I really doing what is best for the kids? This is what my in laws are arguing. Now I am only with them 50% of the time and they get alone time with an alcoholic. This is an internal struggle for me as well as one that gets thrown in my face a lot.
Also, I have told my close family members about his issues but they haven't experienced them so they don't really get it. And I don't know how to help them understand.
