Well I wouldn’t say I stopped caring. I still get anxiety in certain situations and that definitely makes me stutter more, but even with my wife, I stutter plenty, and I’m not self-conscious at all with her. But I do think that accepting your stutter and not actively trying to hide it or to not stutter will help you stutter easier. When I was younger though, I jumped through a lot of hoops to completely hide my stutter. Tbh I stutter so much now, that wouldn’t even be possible lmao.
