It is often disappointing when your partner decides to diet especially if you are a FA. I used to get agrivated and argue when ever she would announce that she was going on a diet. I finally realized I shouldn't fight it. Its her decision, she knows my preferences and has not tried too hard to lose. Yet every 6 months she says she is going on a diet. Sometimes she loses 5 -10 Lbs which usually is followed up with a gain back plus a few. In the end it seems to be best if you don't fight it because it may turn out better.
