Am I wrong

So this is the third time my fiance has corrected how to say a street name. My whole life I've pronounced it a certain way and he says no its spelled like this. This is how you say it. I say oh ok. And somtimes say it his way or sometimes move on to the point of what I was saying. Today he said that I should pronounce it the correct way. I didn't even think it was a big deal. He said because whay I do and say affects our family (we have a toddler and one on the way). So me not pronouncing a street name is going to make people view us bad? He said that people are going to see that he's not with an educated women. And with my hormones and just getting out of urgent care for being sick. I just lost it. It's absurd to me. And it hurts my feelings. I don't appreciate that. But he says that why I can't I change toe pronunciation because he asked me to and because it bothers him. He says it's so simple but that isn't the point. What should I say or do?
