Why do my in laws always want to visit us? Even if I’m dying my husband says yes to their visit.

I guess they feel a need to be as close as possible and that's their way of doing it, but they should really ask you, as well. After all, it is your home. That's not right. Have you told your husband how you feel? He should take your feelings into consideration and work this out. In-laws shouldn't "live" at their daughter-in-law's house. You need your space too. And it's especially imposing that they expect a meal all the time. Stop making the meals and see what happens. And start refusing the walks. They should understand if you're tired or just don't want to. Some people are selfish and inconsiderate of others. I really feel for you.
