I think when one person has a mortgage, asking the other partner to pay some money towards that mortgage is quite strange. After all it is their flat and their mortgage...so getting your boyfriend to pay some money off a property you own and he has no share in/will not have any share in seems quite exploitative to me? I mean I don't think he should get to live there for free either, but when you consider any rent paid is paying off Freddie's mortgage on an asset that is only hers I find that a really odd concept. It's totally fair to contribute to bills etc because they aren't an asset owned by one person.I think it would be pretty normal for a couple living together to split the expenses, so if one were paying a mortgage, the other would put some money toward it. But when influencers talk about that on their channel to me it always feels like them trying to emphasize the power imbalance in the relationship. I'd think it was just as weird if a man was talking about owning a house and requiring his SO to pay him rent, too, but it seems like a lot of women influencers do it thinking it makes them admirably empowered.
I don't think they've thought this through though which is again really weird, her saying he might buy his own flat or he might end up living there in 6 months to a year...I don't understand how if she's telling us they're a serious couple these aren't conversations they've had and properly considered already,
