Interesting! We got down to the nitty gritty early (< 6mo into the relationship) mostly because we’re practical and finances are part of thinking about our future. My BF has been in the process of rebuilding his credit, so we talked about his score/my score/our aggregate when applying for apartments together. He just financed a car, so we talked a lot about what things he could do to bump his score by a few points beforehand (debt to credit ratio, hard inquiries on his credit, etc). It’s just another thing we talk about, no different than figuring out what to eat for dinner.
