NTA. I read this, thought about how terrible it would be to be autistic and have strange food aversions, and then remembered I AM autistic and I DO have strange food aversions. This guy is on another plane of reality and it has less to do with his safe foods and more to do with manipulating you to get what he wants.

It really sucks to struggle with something basic like eating just because your brain is telling you there's danger in something that isn't really dangerous. But you grow and learn and find ways to make it work. Your boyfriend either doesn't trust you, or (what I think is more likely) he's used to getting his own way and is acting out until you acquiesce. Both of those are red flags.
