I agree with some post, it is the time to focus on OP's own health problem rather than husband's attitude.
I would like to share some tips on losing weight. As I gained some weight a couple years ago, and found it is really hard to lose the weight. But I managed it slowly. First, I weigh myself everyday, you do discipline more if you see you weight everyday(use a digital one, so you can see the smallest change).Then I adjusted my meal to 3 small main meal plus 3 snacks. As I can't bear to be very hungry due to my stomach. Be careful about the diet, I think you need enough protein and vegetabele and Fruit. I have a small breakfast, just a plain toast, an egg and a fruit. Morning is a good time to be displined. Then when I am really hungry 3 hours later, I will have one biscuit( you can compare biscuit, find the low energy one, and after a few weeks, I found I don't fancy the biscuit for the morning anymore). Lunch is light too, similar to the breakfast, you can have chesse instead the egg. Then afternoon snach, some fruit and nuts, one biscuit allowed if you really want it. I eat my dinner with mainly protein and veggi. Then I will have no more than 2 biscuit or rice cake before sleep. That's my habbit, if you can skip this snack , of course it is better. I lose 1 pound every few days on these plan.
As for exercise, I choose walking at the weekend, then light yoga everyday. I think it is better to choose something you enjoy, like dancing with music.
And set a realistic goal, lose wight slowly rather than hoping a quick lose. The last and most important point, is having enough good sleep. Lose weight is quite energy and emotional consuming.So you need your good sleep.
