Okay, there's a reason these people were all an Ex. Why people want to go back is beyond me. Peter in particular needed to man up. Diane was way too controlling and self-centered and he acquiesced and deferred to her all of the time which would only lead to frustration and resentment on his part further down the road. I wanted to tell him to run away hard and fast once her true colors started coming out. The only one who did the right thing was Lauren, who was honest and said it wasn't going to work. She knew she could do much better than Erik. Meg and Jeremy are both too selfish to share their lives with anyone else. Kate and Cam were the most level headed, which was really surprising since they were the youngest of them all. However, all were doomed from the get-go.
