So when she asked you why you repeated a word you laughed at yourself instead of telling her you stutter? When someone suggested you watch the King's Speech (who sounds like she was your friend by this point), it couldn't have been because she thought you'd like it or take something from it? Your comments about her sleeping with someone else clearly means nothing, she can sleep with whoever she wants when you are just friends. If you didn't want to hear her problems as a friend, you could have told her you weren't interested in any new friends at this time. The problem here is not stuttering, (Edit: no matter how many times you downvote my opinion)
