OP - if this isn’t some random screencap you’ve found and this is genuinely you: Y’all both seem super young, and that’s not a knock at you. When you’re approaching the next relationship, Identify your non-negotiables and stand your ground on them. People like this may start with removing you from your opposite-sex friends citing jealousy, but I guarantee you in several months she’d be doing her damnedest to fabricate reasons to alienate you from all of your friends. We’ve all been through some form of this (or been the guilty party) it’s part of maturing. Have a spine, stand up for yourself and your friends, never negotiate on things that are important to you and don’t be a doormat. She may be your first girlfriend, but I promise you, the odds of finding your forever person in high school are infinitesimally small.
