I guess it depends on how much you really like the person you are sitting across from.
My spouse (married over 30 years) sometimes "forgot" his wallet . I (the woman) paid. It's cool....I liked him. He is the ONLY guy I really liked. We were best friends then and still are. We are very fortunate (as JW's would say...blessed).
There may come a time in life when the wife makes more money or has to support the family financially. It's no big deal, we are a team and the money goes in the family "pot." That may not work for some, but it worked great for us. It still does.
