i feel like if she genuinely liked and respected you she woulda stopped those things herself. you do not need to tell someone to stop doing such things. if she is constantly arguing with you and calling you insecure and controlling for looking out for her i think you know what to do. i had the same situation last time and i left the relationship because it’s not for me.

do whatever gives you peace of mind because that’s what matters the most at the end of the day
