I don’t think that any of my exes cared about my speech disorder. A guy even told me its cute. However, my point is, you will know if she cares or not. If she lets you speak and doesn’t seem bothered at all, its a good sign that she doesn’t care. Also, unfortunately, with current dating, you will be blocked or ghosted for such a thing. So if she doesn’t do it, you got a normal girl. And, I hate this saying, but its true-if she is the right one, she won’t as I said even notice your speech. But she will notice when you stutter less! And will let you know just to praise you because she will know what a struggle it is even without sharing.
