Boyfriend's Fat Sister Driving Me Nuts [rant] So, I've tried helping her, when we first met. She's 37, 5'6", 260lbs. We all know that doesn't work. I'm 35, 5'8", unsure of my weight because haven't had a scale at home, but it's around 140-145lbs based on my measurements/clothing size compared to the last time I weighed. All of her friends are at least overweight, if not morbidly obese, they're all about our age as well. Every single one of these hogs just blames on getting older and genetics. Here's a list of bullshit I've had to put up with: 1. Cried crocodile tears when her husband said she drinks too much and is 150lbs. overweight. Tried to get sympathy but I just told her that he's probably saying that because she's destroying her health and he has tried everything so insulting/shitlording is all he has left. 2. She is one of the "thin" one of her friends. So, if we have to do something with all of them, I constantly have comments made about my normal weight being odd at our age. 3. At an event, when a friend of hers commented (in a nice way) about boyfriend and I's fit statures, she just glared at me and said, "Yeah, they're clearly not in love, because you gain weight when you fall in love." Nevermind her husband is the same weight at 47 that he was when they met in college. 4. Makes me try on her ridiculous 2X circus tents she ordered for herself in front of everyone bc she's too fat to fit in them. Tries to make me take them home because she thinks we're about the same size. 5. Constantly makes comments about how I'm clearly bulimic because I eat food . . . ?  6. Has been diagnosed with early signs of fatty liver disease (I'm certain it's a combination of alcohol and poor diet, bc she drinks 8 beers each Saturday & Sunday, beer every night and eats shit constantly). 7. I've gotten food poisoning from eating at her house because she's disgusting. Also, she'll invite us over, and fail to mention until after we've eaten that she's had horrible diarrhea/her son puked all over the house, etc. She doesn't seem to understand that I usually take in 1600-1700 cal/day, work out regularly and have a labor-intensive job. Meanwhile, she binges every night, sits all day at work refuses to exercise. I would love to avoid her as much as possible because she's the most toxic person I've had to deal with for a while, but I'm stuck spending every damn Sunday evening at her house. I think I'll try to find a class or something on Sundays so I "can't make it".
