No, your stutter doesn't ruin anything. Read your post again. >Feels like every time i try to tell him a joke or a story ***my brain tells me*** You're ruining your own moment. Have some faith that your fiancé loves you for who you are, and accepts you and your stutter. No matter how long it takes you to say it, just say it. What you have to say is important, don't let anyone tell you otherwise. Including yourself!
