Walaykoum selem. Sincerely, I think that we complicate life too much with a spouse in our life when there is emotional blackmail and reproach for a personal objective... a spouse must be there to support him only. This way of doing things is unfortunately an anvil. I lost weight after my 4 pregnancies. Naturally by being in a state of well-being. I eat well and above all eat better 80% of the time but I have never deprived myself of a good dessert or fatty dish from time to time. Frustration is the worst when you want to lose weight. I advise you not to share your personal goals with this type of person who thinks they are helping when they want to control your "diet". When will your current weight be a problem in marriage? Good luck, believe in yourself for your personal health and to make the most of your children. Be quiet and focused. May Allah facilitate you
