Wife didn't come home
My wife went to a dinner party at a friend's house. Her friend has a side business selling lingerie and she went over to pick up some things she ordered as well as try on some of the samples with her friends. That's why husbands weren't allowed to go. It was a girl thing. I said "fine" and hung out at home and watched sports and had a few beers.
It was getting late, around 11 PM, and my wife hadn't come home yet. I called her, and I could tell that she was drunk. It was also really loud in the background, music blaring and loud chat. I offered to pick her up, even though it was only a few miles away, but she said don't worry I'll be home in about an hour.
I went to bed and woke the next morning and she still hadn't come home. I called her, but got her voicemail. She eventually rolled in at 9:30 AM and her blouse was wrinkled, hair was a mess, mascara slightly smeared, and the lipstick she put on the previous evening was gone.
She said she realized she was too drunk to drive and didn't want to bother me, so she stayed over. I asked if she had sex, but she said no. I don't know. She immediately took the lingerie she had in her bag and washed it right away. That made me suspicious, but maybe I'm overthinking things. I don't have any reason to suspect that she ever has cheated on me in our 6 years together, and don't think she's bi, but this one makes me wonder.
