I deleted my previous posts as I said I thought you deserved better, but think my comments were taken the wrong way & I don't know your situation.
I really liked kebakat post, I think it was well said & so true & I know she has put the effort into getting where she is now.
A life style change is all it takes & you can do it at your own pace, like swap fizz for water then challenge yourself to drink more of it....& so on, & it wont take long till you consider the changes just a normal day.
For me when I am in the weight loss zone it is like a light goes off & I want to do it so the motivation is there. The weather plays a big part for me so I have noticed & these lighter, warmer days make me want to get moving.
The only real way to lose weight is to eat less & move more & there are lots of support groups out there & in here. At the end of the day you have to want to do it.. & you have to do it for you & no one else.
As for your DH if your weight bothers him that much then ask him to help you, he can cook his own meals or eat crap/takeaways out of the home. Go for walks together at night, but don't rely on him to do it for you or let him hold you back.
My DH hates to exercise, but loves to game, he bought us each the EA active2 set for the PS3 & every day we both do it, he is so focused & has lost weight, we both have & we are having fun.
It must be hard working in the bakery but just think when you reach for that cream cake about how many calories there are in it & how many sit ups you will need to do to burn it off...then ask yourself is it worth it???
And most important just because you are over weight does not mean you can not wear nice clothes & look good & feel good & have pride in yourself & when you are ready to lose weight for what ever reason you will do it.
