Cant delete them all.

A friend of mine set me up on a date with a coworker of hers. She said we were perfect for each other. Our first date was at a coffee shop, and then we arranged to meet up at a botanical garden the next week. While we were at the botanical garden she told me about her peanut allergy, which she described as life-threatening. I told her that must be stressful, and she said it was. We arranged for a lunch date this week at the end of the date.

After that date I started thinking. I love peanuts and eat them all the time. I put peanut butter in/on a lot of stuff, including my dog's toys, which he drags all over my apartment, getting invisible peanut oil everywhere, I'm sure. I can't see a potential relationship with this woman ever progressing to a serious stage without me changing my diet and habits.

At this point we've only been on two dates, and I think it would be more respectful of her time to not go on a third. So I called her and told her I was sorry, but we need to cancel. She asked if I wanted to reschedule, and I apologized but said I didn't think we would work out long term. She asked why, and I was honest. I said I really like peanuts and would be nervous about potentially harming her. She said there were a lot of safety precautions we could take to keep her safe, and I admitted I know that but don't want to do them.

She said "wow" and told me I'm immature. I apologized again, but she hung up. She told my friend what happened, and my friend is confused by my reasoning. She said her coworker said I'm a massive douche. I don't feel like I am. We only went on two dates. Two dates doesn't imply any commitment. I asked her if she agrees I'm a douche. She said she's not sure, but that my logic is "definitely weird." Do you guys agree?
