DS is looking to buy a house with his GF.
My Dad has always had loose plans that he'd help DGC with their first homes, although GC don't know this and certainly aren't expecting it.
Dad has a very fixed idea that they shouldn't buy together unless married, so therefore won't be helping, which is his choice, but I can't get to the bottom of why.
I think if they can do it without help, that might actually be better anyway, as there's a lot of satisfaction in knowing you've worked for what you've got, but leaving that aside, what might Dad's thinking be?
He's not religious, I don't think this is anything to do with moral policing, more the security aspect, but to my mind it's easier to protect DS's half if they're not married, if that's the concern?
