I'd say that such a relationship would actually prove to be better for us. They say that the person who cares less about a relationship has the most power over it. If you were madly in love with your partner then you'd be paranoid about her leaving you and if she did, it would destroy you. However, if you weren't that attracted to her, you would care less and would probably behave more aloof and demanding towards her because you know that her leaving you wouldn't be that much of a big deal.
Also, the Chinese have a saying "the ugly wife is a treasure in the home". Meaning that attractive foids will put in less effort into relationships because she feels like she already brings enough to the table by merely being pretty. Meanwhile, an ugly foid will know that her looks have no worth and will attempt to bring more practical value by cooking for you and stuff like that.
