Weight Loss/Maintenance

I just lost my partner, the absolute love of my life, because of long term complications of diabetes (got its start before I met him)... yours is not an easy journey

take care of yourself and your daughter, be an example w/o harsh criticism
cook healthy food for everyone
you cannot (and should not) control your wife... she really has to be the one in charge... if she eats a bag of chips, it does no good to judge her (it is most certainly your wife who is her harshest critic and she doesn't need more)
listen to her if she wants to talk about her health concerns and ask her how you can help... let her know you are there if she needs help

somehow though, it is good if your wife had a "reality check" about what diabetes can do to hers and/or any person's body... loss of limbs, heart problems, kidney failure... it's not pretty

and don't listen to people posting here judging you... you don't need that
