Misled By Wife Years Ago

Years back when our kids were young my wife flew to NOLA to meet her gfs for a festival. Years later her friend has all her pics put on dvd. There were pictures of several guys that I recognized as part of her old group of friends. Only one of her two friends were married and her husband wasn’t there either.
Why would she have misled me like this, she says she didn’t, she was going to meet up with her two gfs but there were five other people in the group and 4 were male.
