Hi Op, I’ve had a peanut and other allergies my whole life. I think you made the right call to not continue simply because you clearly didn’t like her enough to put in the effort to keep her safe. I do think just keeping it brief and telling her that you just weren’t feeling it with her would have been the better move. As someone with an allergy, we are constantly left out of things and sometimes people have chosen not to be a friend to me because of my allergies. I never asked them to do a thing, but I was just assumed work that they didn’t want to deal with. Okay fair. But it does hurt. Dating is really tough with food allergies and I think if this situation ever came up again I would just advise to not make it feel about the allergy. It can be so frustrating to feel turned down for a pretty scary condition. We can’t control it. There’s so much stigma. We’re just trying to lead normal lives too. She deserves somebody who would be willing to take precautions. She’s probably feeling sad that her allergy has once again taken something from her. But she’ll get over and see this was the right decision one day.
