It's another MIL one. My DH's mother has a chronic illness and is in and out of hospital a lot. This has resulted in mission creep with him doing more and more and I seem to be getting sucked in (and starting to resent it) DH has a sibling but they are utterly useless and do absolutely nothing. I obviously want to support my husband, but I also do not want my forties to become overshadowed by someone else's I'll health. I also think my husband needs to place more boundaries, but that is actually between him and his mother. I just want advice on how to make sure I dont get sucked in to doing more and more. It is affecting my mental health. Has anyone else been through similar, and if so, what do you advise?
