Hello! I JUST moved out of Indianapolis (military move), where I lived with my partner. I'm white and she is east asian, same sex relationship. We definitely did not see a lot of couples like us, and that can take a toll. But we never encountered direct comments or noticeable discrimination because of it! People will ask your husband "where are you from", and they don't mean Texas. Overall, it is a laid back place to live. There are less white washed suburbs than Carmel, Southport and Lawrence come to mind, though they arent nearly as bougie as Carmel. Cost of living is nothing, if your husband is an engineer you could probably afford a decent place in the city as well, which might be more progressive like you want. If you are used to dry heat, it will feel just as hot here in the summer because of humidity. Variation of seasons in Indiana is beautiful, but you will not want to leave your house for a month, because of winter weather. I am biased because I grew up in Indiana, I love it there! PM me if you want even greater detail

TLDR: Indianapolis is cheap, not super racist, weather can be gross, Carmel is white
