My family consists of my wife, my 3 young children, myself, and now my father in law. I've shared the story before, but as a reminder my in-laws moved in with us and my MIL passed away from kidney disease within 6 months. It was traumatic for everyone as she refused to take care of herself and also refused help. My wife still feels guilty for not saving her so she is trying to do it with her dad. We have discussed simple rules like keeping his room clean, not spending money, not eating in his room etc, but he does what he wants. My wife has now assumed her mom's role by not holding him accountable, and doing everything even though he is able bodied. We fight, at times, and I feel powerless because my wife is unwilling to talk about anything related to her dad. As a perfect example of his lack of respect for his daughter and my family, he had secretly decided to marry a woman (less than one year after his wife of 40 years died) and move her in without telling his daughter. He was going to do so in order to help this woman to become a citizen. This brings with it an expectation that my wife and I would be supporting him and this strange woman that he met once. My wife overheard all of this on a phone call, but she won't confront him and continues to make excuses for his behavior. I hate the dysfunction and have lost all compassion for a man that continues to choose himself over my wife and children. How do I keep my marriage as I am losing my ability to tolerate the nonsense. I am beginning to feel that leaving will be better for my children because at least they'll have a normal life half of the time.
