You should not let your stutter define who you are. Yes, sometimes things get harder for us, we have to get pretty creative to do things that are just normal for other people to do. Is it fair? Probably not, but those obstacles have shaped you into the person you are right now. Life is less hard if you learn to love yourself just the way you are, with stutter and all. Once you change your perspective, your speech will get better as well, trust me. As others mention, you probably dodged a bullet, you don't want someone who will not accept you the way you are. I am not sure about the introvert/extrovert part, I have met people with stutter who are very extroverted and really don't care about stuttering.
