I'm surprised that having placed the OP's Mum in a home for emergency respite for a week whilst her husband was in hospital social services didn't first check whether her husband would be able to manage her care prior to discharging her home, particularly as she received a huge skin tear whilst in respite. It would have saved a lot of stress and pressure all round if they had done so.
The idea of Dad going into respite with Mum may work but is likely to reduce the number of suitable homes even more as double placements can be difficult to find, especially in an emergency situation.
Hopefully one of the local homes that the OP has contacted will be able to take Mum but if not, as others have posted it may have to be a case of accepting the social services placement for a short time whilst you get something permanent arranged. I understand your concerns about the placement bearing in mind what happened during the last one but hope that today's meeting is better and more productive than the last time.
