why joint,why seprate???

Re: why joint,why seprate???

One of my cousins ‘back home’ has her husband living with her and her mum (sort of). Her dad died and she has no siblings at all. Also, her mum has severe health issues (and I don’t mean the ‘standard’ diabetes, high cholesterol etc that so many MILs claim makes them so ill they need looking after). I’m not too sure if it’s a permanent thing, they’ve only been married about a year.. Also, the couple live in an annexe so they aren’t sharing a kitchen or bathroom or anything..
