I accidentally discovered a new side of my wife yesterday

I was overjoyed when my wife gave birth to our baby. I love her more than anything, but I was just a little worried about how bad things were going after the birth. I decided to relax and go to sleep, and I was relieved when my wife said she would be okay. When I went to sleep, I was really happy and relieved that everything was going so well. The next day, I felt a little weird when I woke up. I rubbed the sleep out of my eyes and my wife was sitting on the couch in the living room. I was confused, and I asked her how she was there. I asked her what she meant, and she said, "I'm talking about how we're going to raise the baby." I said, "But how did you get here first?" She said, "We were sitting in the tub together, and we got in a fight and you went to sleep here." I was shocked and said, "What?!" I went to go check on the baby, and when I opened the door, I saw the woman I was dating before my wife. I was in shock and she said, "How's it going?" I said, "I thought you were dead," and she said, "No, I'm fine." I said, "But you had a baby. I felt it kicking, and you said you were having a miscarriage." She said, "No, I was never pregnant." I said, "But what about the baby we're going to have?" and she said, "There is no baby."
