Hello! I know how you feel, you’re actually braver than me as I am scared nuts to pick up the phone, but personally, in my relationships I don’t talk over the phone at all; we both live close and if not we text. All I can say regarding a stutter in a relationship is that sharing feelings is very important. You have to let him know your thoughts on your problem, as this is now a part of you and he will have to accept it normally, as I accept that some people wear glasses you know. It’s not as much of a big deal, the person is with you because he likes you for who you are and most likely for how you look as well. Love really tears bad qualities away in the eyes of the lover. We give it more attention that non stutterers do, I’m sure he has all the time in the world to hear what you have to say!
