If the above is accurate and not an overreaction and imagining the worst on your part - if indeed he will finalize plans for their arrival and inform that to you as a given after the tickets are booked, if your obvious total disagreement will not make him alter his plans, then, any discussion you try to have with him will simply make him dig in his heels even more. The risks for both your in-laws, your kid(s), and your financial future are things that experience has shown me: a person gets it by himself/herself or doesn't. These cannot be explained. Tough situation. It has come up because in general your husband thinks it is ok or gets away with making such major planning without your continued participation. If I were in this situation, the risk he is willing to expose my/our kids to would be a deal-breaker. My duty to protect my kids would be way above my "it will be my fault if they fall sick alone in India" fears. I would give a pause of few days to the discussion, keep things normal in other conversations, and then calmly "inform" him that he can bring them if he is willing to have them stay in a separate place right from day one picking them up from airport. I would make this known to in-laws and BIL/co-sis also, if needed. They are saying a plain No, you are giving your husband an option to have his parents close by. The main reason would be: kids will go to school and other places, you will go grocery shopping etc, and this will put his parents at risk. The smaller stuff like how husband will visit them frequently, how to avoid them coming over for entire weekends, I would leave to sort out later. This would not be an empty unenforceable statement from me to him issued in frustration. I would be prepared to move out myself with the kids if he still goes ahead and brings his parents to live in the same house. Such behavior from a husband - always talking about bringing his healthy parents over for long durations or to settle here - while knowing wife is not in favor of it, and husband not willing to look into live close by but separately options, put enormous stress on a marriage. Such stress in a Covid kind of situation turn out to be the last straw. Even if the marriage is otherwise great, and he is a "great dad and great provider", I would seriously look into options like living separately irrespective of in-laws plans.
