My gma broke her hip and was in rehab for 3 months so my husband thought she would be fine as long as she gets home and into her routine. Of course an 85 yo with middle stage Dementia is NOT going to get better it's going to get worse. So he decided he would take care of her. That was a very bad idea. After a couple months he couldn't handle it anymore and left. She got bed bugs so APS took her out of her apartment. They are not giving him any info as to where she is or what's going on. What happens when APS gets involved?
Grandma is probably the subject of an ongoing investigation. If he behaves himself and nothing worse than the manifest neglect comes to light, in due course he could apply to them again for information.
If she is made the subject of a guardianship application then someone in the family will need to be told about that. Where are your husband's parents?
Someone called APS and she has been removed from her apt. They probably have temporary guardianship and will go for guardianship. He may be informed when the court date is.
Hopefully, she has been put in a nice LTC facility. Where are this woman's children? At this point, I would just allow APS to do their job. You husband has shown a level of immaturity in handling this situation. Gma should have been transferred to a LTC facility after her rehab stay.
Be on guard, hopefully you never become sick because u won't be able to depend on this man.
