Sounds like a toxic guy... my dm’s are ALWAYS open. Lol jk. But this reminds me of a similar experience I had with my EX gf (I’m single). lol sorry. Anyway... I decided one day to tell her about my stutter. Kind of like a coming out. I was always curious if she even knew or had a thought about it in the back of her mind at least. So I told her one day straight up. And her word for word response was: “oh you’re just tired”. And that was the day I realized that people don’t even know what a stutter is.
