The community on My Fitness Pal is very supportive and you can buddy up with others.
The advice on here about taking up jogging etc, when obese is a recipe for strains and ligament etc tears, I was advised to lose two stone before doing anything accept walking, to protect my joints.
Then, as said I cut my budget to afford the gym, but if I was on single person benefit levels, I wouldn't have the budget to play with.
My Fitness Pal and similar forums helped me think more in terms of strength, bone/muscle health and fitness, losing weight and being toned, was a by product of that.
I don't weigh myself, I take my clothes off and look in the mirror, as well as logging my measurements.
You can't do it quickly, that's what keeps people in a yo-yo diet cycle.
Your DHs habits are irrelevant, your body's needs, as a Woman, are different, if you have a goal in mind.
I would recommend trying to lose body fat before you go through the menopause, only because you are still making collagen and your skin will respond better. I've had to have body wraps, use dry brushing (which is good) and moisturise to stop my skin being crepey from weight loss.
