If this was a one time thing talk to him about it. If there is a pattern forming where he is constantly critisizing you and insulting you, esp. when ever you lose weight or do something to better yourself, you might try a counsler or clergy counsler for both of you. It could be he is insecure about your weight loss, or feels a need to be controlling with out even realizing what e's doing. Having a third person to help you two learn to communicate could make you both happier.
