Have you been to a group home?
Frankly, most individuals in a group home are capable of much more than Abbie is. And yes, in a group home they are taught to open doors and gates, cook, cross the street....they arent sitting in padded rooms like an institution.
A&P are garbage, but we know Asa loves her. She would not be "loved" in a group home, she would be cared for by people who are also caring for 3 or 4 others. Abbie would regress and lash out, self harm, end up rocking in restraints and doped up.
I worked in a group home for nearly a year. She would have to be not only in a very high level home, but you are right- we would not be able to handle someone like Abbie. My clients were mostly able to care for themselves (hygiene) if they were prompted. We made sure they had their meals and meds, their home was clean, but they were able to manage themselves much better than I have ever seen abbie do. She will always need intense one on one care. The best we could do for her would be to medicate the hell out of her, as we simply dong have the resources for someone of her needs.
It sucks and is sad, but is true. I'm glad that summer and Isaiah seem to care for abbie as much as they do, because someone needs to watch out for her after Asa and Priscilla pass away.
