how do I deal with my fiance's hints on my fatness?

OK I know I went from fit to fat. This medication has my metabolism out of whack. it's been a nightmare. I am not an idiot. I know how to exercise and eat right. anyways, I meal prep healthy meals for the week and workout 1.5 hours a day. I do strength training and treadmill hiit sessions. I have even been starting martial arts training. it annoys me when people make rude comments about my weight but haven't a clue what's going on with me medically. I never struggled with weight until being placed on these drugs. I was actually a fitness guru and studied it in college. I feel alone alot because no-one gets it except the people I have met going through the same issue. It reassures me there is hope when they tell their experiences and it mirrors mine. anyways, my fiance has been pressuring me to workout twice a day even three times. I feel 1.5 hours a day is enough combined with healthy eating. He also monitors my eating which is annoying because he's eating a 5Lb bag of m&ms; while I am eating green beans and roasted sweet potatoes. it's super annoying! This experience has changed my view of fat people' people are so rude to them. How do I deal with my partner?? *** just wait until I get my gorgeous body back....I am going to tell these fuckers to fuck off. people are extremely rude to overweight ppl
