Most families do not decide to stop keeping the promise. It thins out one exception at a time. She asks for her shower to be moved to the afternoon, so you come over at lunch. She skips the walk to the mailbox, so you pick up the mail on your way in. A night you planned to sleep at your own house becomes a night on her couch because the chair is not quite right. Each choice makes sense on its own. Together, they can mean the house is holding nothing except you.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
Keep the exception log for two weeks
Pick a notebook or a note on your phone and, for the next two weeks, write down every time you changed your own plans to keep her in her own house. Write the task, roughly how long it took, and whether she asked you to do it or you offered. Do not judge the entries yet. The point is to see the shape of the week, which memory tends to smooth over.
When you read it back, look for three things. Which exceptions came up more than once. Which ones she accepted without asking, because she has learned that you will say yes. And which ones you would have to keep doing for the promise to hold through a bad week, not just a good afternoon.
Separate the repeating tasks from the one-off favors
A one-off favor, like driving her to an appointment you could not have guessed, is ordinary family life. A repeating task is a sign the house has a gap. If you are doing the same thing every morning, every evening, or every Saturday, the question is no longer whether you can manage it. The question is who else should be holding that piece: someone else in the house, a neighbor, a paid helper you can afford, or the care team.
Write each repeating task on its own line. Next to it, write what would have to be true for someone else to do it reliably. Maybe it is a set time, a key that works, a route that is lit, or a helper who knows what she likes. Some answers will point to changes in the house. Others will point to a conversation with her about what she is comfortable with someone else doing.
Ask whether her yes is still hers
Sometimes the exceptions grow because she has stopped asking for things. She may say she is fine, that she does not want to bother you, or that she will wait until you come by. That quiet can look like the promise working. It can also mean she has learned that asking costs you something. Ask her plainly which parts of the day she wants kept the way they are, and which parts she would be glad to have handled differently. Her answer may change the list you just wrote.
What to bring to the care team
When the log shows a task that keeps landing on you, the care team is the right place to ask what they can add, what they can change, and what they would need from the house to do it. Bring the notebook. A list of what happened, in order, is easier to act on than a general sense that you are stretched thin. Ask them to say which parts are theirs, which parts are yours, and which parts might suit a hired helper, and get that answer in writing if you can. A helper can keep her company or run an errand, but decisions about her health stay with her doctor and the care team.

When the bending becomes the plan
A promise that only holds when you cancel your own week is not yet a plan. It is a warning. You do not have to close every gap this month. You do need to know which gaps you are covering by yourself, and whether you could keep covering them through the worst week you can picture. If the answer is no, the house is telling you it needs more hands than family alone, and that is information you can act on without giving up on her.
