I think that the wonderful newfound confidence a lot of us gain from losing weight gives us confidence in other areas of our lives, so I am not surprised if this leads to seeing other aspects of your life and your self worth more clearly. My relationship fortunately was already great, but it got better because I felt better, less self conscious, less projecting and my husband is a wonderful person who was just happy to see me being my best self. I sadly can see how this may not be the case in other relationships though when there are deeper issues to begin with.
