Your frustration is completely normal! And it's completely normal to take a couple of attempts to get through your second round (Melissa has posted about the second time being more difficult, here: https://whole30.com/2015/02/second-whole30/)
I understand why you would want your husband to join you for moral support, and I also understand why it may be difficult to have him to eat the food you prepare but not abide by the full set of rules. Here's the thing - you've successfully completed the program before, on your own. You can do it again! Perhaps you may need to have an honest conversation with him and let him know that it's ok with you if he doesn't join you on this round, but also explain how much time and effort you've put into preparing the food that you're eating and the leftovers, and asking if he could find something else to snack on before dinner if he's hungry. It would be a little extra work for you, but you could also prep some chopped veggies, hard-boiled eggs, etc. and let him know that those are available for snacking, but you would like to save the leftovers for your meals.
I like your plan of preparing your body this week and starting over again. I often challenge my clients to eat at least one meal a day completely Whole30 for the week before they begin a round. This can help to prepare you mentally for beginning a round while also making the hangover period much easier.
