Hi Ashleolucky
Welcome to TP. I am sure you will find a lot of support in this forrum.
From my personal experience, my MIL lives with us and can get very argumentative. The trick is to just agree.....even if you don't! Trust me your Dad will feel a lot less frustrated if he can just keep on mind that it is the illness making her this way.
I sometimes sing "let it go" in my head, grit my teeth and move on. There is no point in trying to change the point of view of someone who has dementia.
It seems like your Dad is in need of some time out and there are a lot options besides a care home. There are companions, carers, day care centres etc. All these can give your Dad some time off. You don't say if your Dad has applied for attendance allowance. We use ours to have a companion come in 4 hours a week. MIL loves the different company too. She is a "friend" rather than a carer. And this is how we sold it to her to start with.
Also your Dad should be arranging respite care for himself...maybe he could go away for a few days and you stay with Mum to give him some time off. Or take her out on specified days to give Dad some time out.
Get Dad to join this forum and let him read up on all the other people in the same boat. It sometimes helps a lot.
