Easier said that done, but ask her how she feels about the stuttering. And don't be afraid to be honest about how it makes you feel when talking on the phone. If it's clear that the stuttering is a significant issue for her (and from what you say, it looks like it might not be - but as said earlier, it's important to get clarity on it), then she isn't the woman of your dreams. And as for your question, it's been a while since I've been in a dating situation, but when I have, I just don't think about my stutter. If someone has a problem with it, it's a problem with them, not me. I did date one person a while ago who mocked my stutter when she was being particularly vindictive. Having been used to others making fun of me or giving me weird reactions because of my stutter, I just laughed it off. Like, really? That's what you're going to use to try to get at me? What are you, ten years old?
