It was two months after we married and I wasn't immediately aware but she did admit to it.
A girls night out that I was expecting her back from in the early hours but I received a message instead, telling me she was struggling to get a taxi so was going to ...... at her friends house which was close to where they were out clubbing. I texted back but got no response until the next day.
Anyway, I wasn't sure how to check so instead I called her bluff and asked her about her night and she told me how she left the club late with her friend. I said that my friend was out clubbing and saw her in there and he'd told me she left earlier with a guy and she responded with "yes, that was a friend of her friends, they left to get some food". I said I thought it was just her and friend at the house and she said it was so I said I was worried about her so called the house and someone picked the phone up, i think it was her friend, and I could hear male voices and music and laughing then the phone was put down and she said "oh yes, well he came back with a friend for a little while then just fell asleep". I pushed a little and then she admitted that she'd spent the night with a guy she'd met at the club.
I was shocked to be honest and didn't know how to react. I was annoyed at being lied to but she said she wouldn't lie again and I dropped it rather than create an argument. But then nothing for a long time after that until we started to explore cuckolding as a couple.
