Someone who doesn't like you just because you stumble over your words is someone you don't want to be involved with. Seriously, she's not worth the time and effort if she's that way. If she was the one for you, she'd want to get to know you as a person other than a stutterer. I'm introverted as heck too, it's too easy to be shy when your confidence is down because you stutter over every flippin word, but try her out and see. You're not any less of a person because you stumble over your words, and it'll be obvious she knows the same the closer you become. Hope it all goes well, good luck.
