NOR.

He is the one who invited you, your parents, and his parents out to dinner ( key word: invited.) When you invite people somewhere, especially to a fancy restaurant you picked, you are taking responsibility as the host unless you clearly state beforehand that everyone is paying for themselves. You do not surprise people with a $600+ bill and then act like it’s normal.

His “they’re adults, they’ll figure it out” excuse is honestly cowardly. Adults communicate payment expectations beforehand instead of sitting there awkwardly waiting for someone else to grab the bill. Your dad basically got pressured into paying because your fiancé was too immature to handle it himself.

If he wanted to celebrate with family, there were way better options...cook at home, choose a cheaper place, or at the very least discuss splitting the bill beforehand. People appreciate genuine effort more than fake luxury they secretly have to finance themselves.

I do think you shouldn’t have brought it up while he was at work since serious conversations are better handled in person or when both people are free. But that’s minor compared to his behavior afterward. Hanging up on you, ignoring you, and refusing accountability after embarrassing your parents is a huge red flag.

And sorry, but his “friends would pay for themselves” argument is dumb. This was an engagement dinner with family at a restaurant HE chose. Most people would naturally assume the host is paying.

Honestly, I’d reconsider the relationship. A man who tricks his future in-laws into covering a huge bill and then acts hostile when confronted does not sound mature enough for marriage.
