My DH has some serious food issues and eats a very restricted diet. I am autistic and don’t have food issues, but it’s something I easily understand. He has his own medical background that plays into his food aversions. It has caused some strife in our relationship, but all that was really required was for me to stop cooking for him.
There are occasional times where I look at a restaurant menu and decide that it’s not a good fit for us to try together. That doesn’t mean I can’t go with someone else or even on my own.
He enriches my life in so many other ways. Finding someone who enjoys the same food I like is actually easy. Finding someone who wants to read the same books and dissect them, who likes my esoteric tv series, or who really understands me as a person is much harder. I can overlook a little rigidity about food.
