This may vary, but as a stutterer, there are times when I speak and I cannot get words out and it causes me to become frustrated + flustered + (enter other emotion here) at myself, and it's not at *you*. And throughout my dating life, I've had people think I can't control my emotions, or I get senselessly upset or whatnot. It's just tough. I feel like many people think this disability is easier to "cure" than it actually is. (Not saying this to disrespect you or anyone). Some days are okay and some days are really really rough. If it was me, I would really appreciate it if someone told me (even during an argument), like, "hey, I'm mad, but I'm not mad at you and I don't want to denigrate your speaking, or put you in a hard spot where you feel the need to say something you don't mean due to what's going on or something. Feel free to text me if it's easier. I'm here for you either way." Other thoughts: Personally, I don't mind when people finish my sentence *only* if they're correctly guessing what I'm going to say. Else, just be safe and be patient. It makes the stutterer less flustered. If all else fails, feel free to ask them. Say hey, I care about you and did my research, but I'd like to know what *you* like. I'd like to know how *you'd* like to be communicated to, etc. I'm glad you're understanding and putting yourself out there to learn. Feel free to ask more questions. We're nice people. I promise.
