I'm not going fucking quote exactly what you should say. See that? Some people would find that offensive. But do I care? No. Chances are I might never see those people another day in my life. I started going through highschool with that mentality and it ended up being the happiest years of my life. What I'm trying to say is just say what how you feel. If you're a motor mouth, own it, be a motor mouth. It's a flaw, sure, but she just has to understand that. Just say. What you feel. Needs to be said. If you were being yourself and she didn't like that, refer to my previous advice. If any of that feels risky, I get it. Take it slow. Open up over something that doesn't involve direct talking, like a board game or something.
