@georgiexox My bmi was the same as yours 15 yrs ago. Also, 5ft 2", so I do understand that it isn't easy and it can be daunting to know where to start. I'd also been a chubby kid and adult, but my weight spiralled after a serious accident.
When I was 40, I reached a point where I was told if I didn't do something about my weight and co-morbidities, I'd likely be dead in 2 years.
That was my wake up call, and I was recommended for bariatric surgery.
Over the next 2 years I lost over 120lbs and reached a bmi of 24.5. I'd lost more than my doctors wanted me to and was left with a lot of excess skin.
I really struggled with this as it was painful and I felt ugly.
I then spent the next 5 years saving up for skin removal and I let my weight go back up to cope with the loose skin.
I weighed around 12½ stone when I had the skin removed and lost about ½ stone from the skin being removed.
This gave me a boost, and despite physical limitations due to mobility issues from the accident, I managed to lose more weight and got back down to a bmi of 24.7
It isn't a easy fix; you get about 2 years where it's easy to lose weight, but then you have to work at it just as much as anyone else does, which is why lots of people regain, even after surgery.
I stayed at that weight for several years, but atm I'm about a stone and a half heavier than I'd like.
That's due simply to inactivity after a few surgeries (hip replacement), stress, and bad habits creeping in as these few surgeries didn't work, so I'm living in constant pain... hence the stress.
My fitness has dropped and I tire easily.
I'm telling you all this because even at my fittest, I'd have struggled in that heat with lots of hills, the difference is though, my dh would've adjusted his plans to take account of my limitations.
Sometimes that means he goes alone whilst I sit in the hotel or a cafe with a book, and it always means we have regular breaks so I can rest inbetween. It also means we alternate busy, active days with ones that are much less active, eg, using a car to get from A to B, pool day, etc.
My biggest regret is that I didn't lose the weight in my 20s.
Like you it went on slowly, 2½ stone with each pregnancy that I then couldn't lose, and another 3½ stone gradually as my mobility worsened.
I don't think either of you are being unreasonable, but his handling of the situation doesn't seem particularly loving or understanding, especially as you were the size you are when you met, so your lack of fitness shouldn't have been a surprise.
Good luck with whatever you decide regarding this relationship and your health. 💐
