Well, he wasn't my spouse, but he had proposed to me that morning. He said he had to go into work to cover a shift, but when he didn't call me for his dinner break, as he usually did when he worked that shift, I got worried (He was an LEO) and called him.
Someone else picked up his phone, explained that the "guy whose phone this is, yeah, I think he went up to a room with his girlfriend, we have it down here waiting for him". They were at a hotel. Turns out he used it as an excuse to sleep with another woman he knew from when they were in the academy together and had been seeing each other for awhile, she was married.
The next morning, when he came to pick me up so we could get our parents to take them to brunch and announce the news, I refused to go with him. In hindsight, I should've waited until we were all at brunch and he had paid the bill to confront him for the free food, but I was young and dumb.
