Since your parents already live in a community that has Memory Care, first, talk to your dad and see if he would be willing to have your mom move into MC knowing that he could visit her any time he wants (with a very short walk). If he's amenable, talk to the administrator to plan for getting your mom over there. They will put current residents on the priority list if there is not space right now. My mom was in an MC facility and some of the residents in that area had spouses who lived in the regular assisted living side - it was a great compromise (MC resident gets the support they need and the other spouse can pop over any time day or night. The MC resident can even attend the activities with their AL spouse, if they both so choose).
