one suggestion i have is if you end up with a dominant feeder, you shouldnt be able to opt out of the activity she wants to do. either you go to one of the food places or you stay home but you are eating something because she demands it.
obviously you still have the skill check option to refuse/eat with her but you cant just stop hanging out with her
also maybe have the feeders sometimes encounter you in the gym if you are there to lose weight and you happen to be in the gym when they have free time, have them try to convince you to either eat something at the gym or go to The Greasy Spoon or Dizzys Donuts if they have that unlocked.
maybe even have the feeders comment on your suspicious lack of weight gain if they keep on feeding you and you keep the weight off by taking the weight loss meds or by going to the gym
also theres a bug that happens where if your partner is immobile and you have "fun" with them, the menu that comes after is the one that pops up for you if you are immobile instead of the regular options. checking her out and exiting seems to fix it.
