Try to talk about the things that has been bothering you and find a middle way to make sure you both are not doing things to hurt each other.
I said narcissistic people .
look forward to your career n make a better future in order to get rid of toxicity.. I've the same issue n i think this is best thing to do rn! just ignore the fact that you've a bad relationship with them n don't expect them to behave well at the same time. It doesn't hurt ever if you don't have expectations.
