Hi nosize2
and welcome!
I identify with the "not getting on the scale by my husband" bit. I was feeling really bad for a few months when I realized how much heavier than him I had gotten. But for me, it was really important to work myself up to telling him what I weigh now. We're on our "weight loss journey" together and I know he supports me and loves me no matter what, so it felt so bad being dishonest by omission, when normally we tell each other everything.
Now we're working together to make our lives healthier and to lose weight. So I'd say if your husband is loving and supportive (I should hope he is!), you should consider letting him in on your weight, and your plans, and everything else involved.
Annnnd I identify with back problems too! I suspect the exercises you can get from your doctor are important (not that I ever did them like I was told to, but I bet it does actually help). Things like swimming are really good because you can take the pressure off your back and still move around and get some activity in. Plus you get to sit in a hot tub after, which feels SO GOOD.
You'll be able to add a signature and weight loss tracker after about 20 days. For me the time flew by... just check back there after a few weeks and the option should work.
