My roommate and a close friend have been having some issues since COVID starting. I have a more conservative view of certain risks. One is that she wants her boyfriend to come over. He works in a hospital, so he can never truly be quarantined. Whenever we have a discussion she steamrolls over me when I talk about health concerns with how she feels. How can I convey how I feel without resorting to yelling back? It's like she doesn't hear what I am saying. This is a tool I am lacking with people who have that type of personality. I feel like this situation I need to figure out because I am sure I will encounter it again.
