I can't offer much in the way of advice b/c I am still a newbie here but I understand the pain you are feeling. I can relate to what you say about the more you do nice things, the worse it gets. It's the same way with my W. My LL is acts of service so being nice is in my nature. I have read and been told that a WAS needs to cast the LBS in a bad light to justify their actions. When you are nice, it is not consistent with this and hence they are upset.
Stay strong and mind that weight loss. 30 pounds in a month is a lot!
