I suggest you try not to harbor the anger and sit down and have an open and honest discussion about how you need his support and the things he is doing to sabbotage it. Perhaps some reassurance that you love him, etc. and your love will grow stronger by him being supportive and encouraging. If you aren't able to have that conversation, perhaps some couples' counseling? Not to sound extreme but you deserve that.
When I was married, my husband did similar things. He would want me to lose weight but sabbotage my efforts by foods he would buy or prepare, etc. If he was serving my plate, he would pile it high. It eventually became evident to me that, yah, he would love to have a "thin" me but was very insecure in himself and felt I would become more attractive to others. It was actually very subtle and controlling behavior in my situation.
When I went for my pre-op appts, this also came up with the pyschologist. He said some men will get jealous as the woman loses weight (or vice versa) and as the other gets more attention, feels better about themself, etc. It sounds like your husband's comments, food purchases, etc. now are a subtle way of him trying to sabbotage this new lifestyle again.
I hope you are able to stay strong, stay focused and not let his insecurities get the best of you. This isn't just for appearance, it is your health at stake. I hope you have a strong support system around you if he cannot be that for you, such as close family, friends, local support group, etc. Sorry you are going through this and perhaps you continuing to persevere and avoid those "muffins and icecream" too will help you feel good inside about what a strong person you have become!
You deserve this - and yes, 2 lbs. a week is a great goal! Best of luck to you.
