I'd rather toss 10k into a couple emergency fund then waste it on a ring. Most marriages collapse due to money. I recall in my younger days I was with a girl and she dragged me to Brooks Brothers. As a child of poverty and evictions I couldn't understand why anyone who need to spend this much money on a shirt.
Even making well into the 6 figures I shop at Old Navy. Hell, my favorite partner thus far was making 200k or so, and she still used an IPhone 6.
Maybe whenever I meet someone new I'll ask on the first date, would you rather have 10k saved in an emergency fund or a shinny conflict rock ? Her response will tell me everything I need to know.
