Stutterer here. I went from a severe stutter in my childhood to a more mild one as I made my way through high school. You have no obligation to deal with or take on anyone else’s problems— no matter who they are or what disabilities they might face. You need to focus on yourself and there’s nothing wrong with that in any way. What I’m curious about is, do you enjoy being around this guy sometimes too, or is it mostly him who has this one-sided attachment? If you want to pursue some sort of friendship or alliance with this guy, maybe try texting him. However that might not be a great idea either, considering he seems to be getting too personal with you too quickly. People who over share like that are tiring enough, even without a stutter. If you just find yourself exhausted by this guy, try to politely tell him that you’re too tired and busy to build deep new friendships. You don’t even have to tell him that it has anything to do with his stutter. It seems to me that his emotional baggage is more tiring than his stutter. I stuttered severely as a kid (like from age 8-13) and I was very popular among other kids even so. It’s the attitude that matters the most for people like us, and this dude seems tiring as a person as a whole. I don’t blame him for being in a bad place. I was too. But you have no obligation to take that on. Good luck. Edit: also, maybe don’t ask him to communicate with you IRL via writing. That’s the most insulting and emotionally hurtful thing you could possibly do to any person who stutters. If you don’t want this guy in your life, let him know. Just... don’t do THAT.
