I'm going to have to disagree with the idea that 10 minutes can destroy a marriage (at least in this case).
This was consensual act. Nobody cheated on anybody. There wasn't a protracted affair, there wasn't even a drunken hookup with a stranger. This was a consensual situation. That the husband withdrew after it, and kept refusing overtures to talk things through, and wouldn't go for counseling? Sorry, the only reason the 10 minutes mattered is because the husband intentionally torpedoed the marriage. There's a lot more going on here than we know about. This 10 minutes was but a symptom of much larger situations.
I mean seriously...how many of us would give up on a marriage after just 10 minutes of problem? Are we THAT uncommitted to making it work? Or did the "...for worse." part not mean anything? No marriage is perfect. It takes time and effort. Being able (much less willing) to walk away from it all after just 10 minutes shows a serious lack of commitment to the marriage. I think this marriage would have ended anyway, just due to another supposed reason.
