Adult wont eat variety of foods...what do I do?

My fiance only eats about 6 specific food items. He has extreme sensitivity in taste and is positive that anything new will make him vomit. I have been with him for a year. He doesn't eat burgers or anything other than french toast, waffles, Chocolate chip pancakes and chicken strips. He never tries anything new no matter how much I beg. I just finally got him to eat pizza, and now that's all we ever eat. I love him to death, but do I just deal with this, or is there a way to help him overcome it.Adult wont eat variety of foods...what do I do?
maybe if you just show him all the responses you're about to get telling your fiance to grow up and stop acting like a 2 year old....there is so much good food out there and if your hubby is too scared to try food?? well that's just oober lameAdult wont eat variety of foods...what do I do?
ok im a picky person and i have two friends that are really picky. especially my one friend katie all ahe used to eat was mac and cheese and pizza and spegitti o's (sorry thats mispelled) any no one could get her to eat anything else, or she just wouldnt. but now she eats fish!!! and i couldnt even believe my ears. does he vomit from eating specific foods and that is why he wont try new foods? if he doesnt and is just scared to try them tell him that he will be okay cause everyone eats all kinds of food and they are just fine. also something you could try i know this might be kind of harsh but i would give it a try. make something for dinner that he hasnt had before but something that you think he would like and that is really common. dont tell him your doing this but once your done cooking tell him dinner is ready and tell him if he wont eat it or at least try it he has to make his own dinner, and if he makes his own dinner keep this up for like 3 or so days and see if he gives in and trys your food. good luck with this!
