Not me specifically but a friend of mine.
She got laid off from her office job and was having a hard time finding work.
She applied and got a job as a mail carrier for USPS in the rural area where they live.

This was 80% walking and 20% driving.
Over three months she lost almost 50lbs just drinking water and walking almost 10miles a day.

This took her from 230 to 180, another three months and she was down to 150. 

Her husband however was almost 400lbs and had no stamina from what she was telling me.

He always told her he was too tired to help with the kids or to do anything really other than go to work (Sit behind a desk and do nothing after getting home) and relax.

She started getting more active since now she had more energy from being generally more healthy.
She did the shopping so she bought healthy foods that her husband didn’t like and was always complaining.
After about a year and then 3 months of counseling that went nowhere she filed for divorce.

She ended up spending alimony on surgery to remove excess skin from being overweight and making herself feel better about her body in the mirror. Nothing enhancing just nipping and tucking where weight loss and exercise wasn’t fixing like tummy flab, arm flab etc.

She tells me all the time if she never lost her job and didn’t become a mail carrier that she would have been content to stay with him, but after getting in shape she realized how bad and toxic he was for her.

She tried to make it work and encouraged him to be better for himself (She didn’t want to have kids with a fat lazy slob anymore and I don’t blame her) but he showed no ambition or will to change.

She doesn’t feel bad at all about it and is now going out with an amazing guy that challenges her and supports her active lifestyle
