Honestly, you’re too young to be burning yourself up on someone who, by your own words, doesn’t think your feelings matter. Expecting you to walk on eggshells for her feelings while while teasing you about yours is manipulation, and that’s just red flag one. You’re bullet list isn’t conflicts, it’s abuse and manipulation.
I’ve been right where you’re at man. It DOES get better, it just probably not with her. She is not your responsibility. YOU are your responsibility right now. You’re 23, your life is just getting started. Make a fresh start and give yourself some time to work on yourself and heal. It’s advice I wish someone would have given me.
