Same with my GF and my brothers, with my GF it’s not bad unless it’s just a bad week of course but with my brothers it’s most only their names, and funny enough one of those brothers use to hate my stutter when I was younger and would always tell me to “just speak”, but I don’t hold it against him cause he didn’t know why I was doing it of course, that’s the brother I’m closest to now haha. With my parents I stutter worst but I think that’s because I’m just so comfortable with stuttering around them it just comes out more, and around my GF I just don’t think about it much.
