Hang in there Kib. Although your mom is not weak she may be weak in this area and she is probably scared that you are gonna be dynamite for her wedding and she, the bride, won't look the way she'd like. As for the sabotage, there comes a time when you become an adult that you have that big adult conflict with MOM. It may be time for you to be very calm and frank and just say straight out-- I don't like how you are behaving in front of me and I will not buy into it or put up with it. If you want to buy and eat junk and pretend you are losing fine, but I at least expect the courtesy you would give an acquaintance or neighbor and not have you deliberately aggravating me and attempting to undermine my goals. I have a goal and I will work towards it with or without you. When you finally get serious I will be here to help. In the meantime, please allow me to follow ny own healthy path. ---She won;t like it and may use a little guilt on you, but maybe she will rethink her attitude and actions.
Even if you decide not to say anything, at least thinking what you would like to say sometimes makes you feel better.
