Youre getting in your own way. If you keep projecting your insecurities onto her, you'll make them come true. It's a self-fulfilling prophecy. Be chill. Don't worry. Stop warning her. And, for heavens sake, if she invites you to sleep over don't book a room (AND THEN TELL HER YOU BOOKED A ROOM) incase she doesn't like you. If she doesn't like you. You'll sleep there, nothing will happen, and you'll leave in the morning. Be yourself. Be confident. And stop warning her. I've never warned anyone about my stutter, and I do just fine with women. It's all about attitude and vibes.
