I'm 31, almost 32, having stuttered since I was 5. I've never dated or even been close to that. I'm basically where you're at right now in thinking that I'll be alone, and I'm struggling with that reality. I'm in therapy with a mental health specialist for reasons related to this (turns out having never even been on a date in your 30s messes up your sense of self worth real bad). But I don't think a stutter automatically disqualifies you from living a fulfilling life or finding a partner. It certainly makes it harder, but a lot of it does come to self confidence. It's something that I don't have and really not sure I'll ever have. But that doesn't mean you won't even find your self worth and confidence. Everybody's experience is different. I hope the best for you. If anything, finding other people with stutters who have had success in life only makes me feel better that we're not all hopeless lol.
