I think it’s more about life stage than age. Like say she hadn’t gone to college and had gotten into the work force at 18, and was now 4 years in to your same industry. You both had the same job, common references, etc. You’d still have some cultural differences but you’d likely be in a much more similar place in your life. It would make more sense then imo. I think a big part of what makes it weird is just how different your lives are. Which is why the same age gap at like 32 and 45 probably wouldn’t be a big deal.
