Why do people get weird when they ask my pronouns & I answer with Mrs followed by my husband’s surname name?

They seem reluctant to use it, even offended but they did ask and I use their choosen pronouns though i dont quite understand all these pronouns, genders and sexualities. Seems there's a new one trending every month.
