Dear Steve and Shirley, My girl and I dated for six years. Then I proposed to her a year ago on her birthday. Since I gave her the ring her behavior has really changed and she's been acting like we're already married. Like married couples we don't have sex nearly as often as we used to. And now she comes to bed in unflattering pajamas or one of my big T-shirt. Before we got engaged she used to cook dinner for me or make sure we had a nice meal but she rarely does that now. Now whenever we go out she complains about everything from the traffic to the service at the restaurant.......
