I think she’s just being nice, and may not know how to approach someone that stutters. Maybe she does find it adorable? But as a stutterer, I can say that I don’t think my stutter is adorable and you probably feel the same. Once you get to know her on a more personal level, tell her how it makes you feel. This will diminish all of the uncertainty and the unknown. Helpful?? Maybe not, I tried haha.
