Just pull over, tell your wife that you are not capable of driving anymore, until you have had some rest. Wish her a fun night, and go to sleep. Seriously.

Fatigue is a serious concern when driving - Up there with distraction and intoxication for how dangerous it can be. If she's not willing/able to take over driving, it's only reasonable to find somewhere to stop so that you can have a proper rest before continuing on. And I do mean proper - Not just like a 15 minute break or whatever - 7 hours is pretty much equivalent to an entire day's work, so you might need an entire night's rest to properly recuperate to the point that it's definitely safe to drive several more hours.

Your wife sounds like a ****!! time for a new one 🤣

This does not sound like a healthy relationship, even ignoring the part where your wife chose to endanger the both of you by forcing you to drive while exhausted. Please seek counselling or consult a divorce attorney, because whatever she’s bringing to the table, it’s not worth it.

When people show you who they are, believe them.

I wonder if that was even alcohol in that flask. Also, your wife is a bitch.

it sounds pre-planned. prank her back by serving her fake divorce papers
