My most recent x claimed this all the time. I gave her the benefit of the doubt since she did have Unicorn I like sparkly things and the word fuck shirt. But her obsession with eating fast food and being just fucking fine after always irked me. Then she would claim intolerance with the most ridiculous things. Like refusing meatballs that had 1/4cup of bread crumbs. Across 40 of them. Then go eat eggos as a snack later…. best part was when she had an new doctor that wanted to get up to speed on everything. The doctor ran a shit ton of tests and proceeded to tell her, on speakerphone In front of me, that she had no gluten allergy, intolerance or half of what else my x claimed she had. But guess what…nothing changed, except our relationship status.
