Tell her openly about how much you like her and how you wanna stop the fights. Acknowledge your feelings
talk to her, tell her what you feel and what you expect from her. And even after that she continues doing the same, Don bother because you have expressed earlier what you feel. If you go to her complaining again that'd be an insult to yourself!!
yaah she too know
