Hey Tigs, glad I saw your journal
My Sweetie is also not even a little bit interested in giving up bread, pasta and sugars. No real big deal with the majority of my eating plan. I just cook Primal meals and add on to her plate the stuff she likes. A piece of bread or a little pasta. Maybe a white potato every once in a while. We have one pantry/cupboard that is non-paleo, the rest I have cleaned out. So basically, base meals can be primal, use good fats, and keep you on track. Non-primal housemates can add on what they desire without affecting what you eat.
As for lifting heavy things... start out slow with the body weight exercises. Spend a little time every couple of days or so doing a couple easy sets. Once you get in the habit you may begin enjoying it I still have restrictions on what I can do physically, so I use resistance bands to get in some strength training.
You are doing great and I am looking forward to following your successes
