Let's rewind: on the last episode of Lactose and Unbalanced, our allergy-prone host braced for another round of Cheddar vs. The Human Airway, after her brother-in-law's girlfriend repeatedly tried to sneak dairy into their allergy-proof home like a lactose-loving ninja. After two ER-followed visits, a spirited round of bag-checking policies, and the kind of family drama that could power three Thanksgiving dinners, the internet staged a much-needed intervention.

Here's the update, which comes with more twists than a string cheese. The homeowner provides further clarity, reminding us that this isn't about crumbs in the trash, it's about the reckless disregard for a house rule designed to keep its owner breathing.

After some soul-searching, the homeowner and fiancé finally take the advice of five hundred strangers: No more second, third, or fifteenth chances.  Brother-in-law, still sporting the emotional equivalent of a Please Kick Me sign, actually steps up, eagerly apologizing, and takes decisive action.

The now-ex’s grand plan to keep him from a fresh start via allergy sabotage was thwarted, along with any future dairy drama.

  • More we didn't know is also that BIL hasn't been happy where he currently lives for the last year or so, and one of the reasons he often comes to visit us is because he has been considering moving to our area. So I have a feeling

  • she has been doing all of the crazy stuff in hopes we would blame BIL, and if we were mad or low contact with him, he wouldn't move. More manipulation, I won't put it past her.

  • BIL also sent out a message to their extended family explaining the whole situation, in case she reaches out to the family, and this way, I won't have to relive the trauma surrounding an allergic reaction to explain what's been going on.
    via InvestigatorHour2911
  • I also told BIL and my fiancé about what it is like for me to have a serious allergic reaction for the first time. What it feels like and the absolute horror I go through. That was definitely the hardest part of the conversation for me.
    via InvestigatorHour2911
  • Neither my fiancé or I blame BIL. The way I see it, he is a good guy who sees the best in people and who has been manipulated by his ex. He is still more than welcome to stay with us, and with
