tough love

This has become a nightmare for my relationship. The basics are as follow: I live with my parents and they are older and in the dangerous age group for Covid-19. My girlfriend has 3 kids that go back and forth between her place and her ex husband's. His girlfriend and her two kids live with him and also go back and forth to their dad's house. Schools are closed, social distancing is supposed to be practiced, the world is in crisis, and she's coming and going from my home as she pleases, multiple times a day, like it doesn't apply to her. I finally said that it makes me anxious that she's potentially putting me and my parents in very real danger. She said I'm overreacting and that it's clear I don't care about her or want to make the relationship work. We've been together for two years. I feel like if she cared about me or my family then there wouldn't even be a question as to whether or not health and safety precautions should be followed.

This pandemic has given me a new perspective on what it means to honestly love and care about someone.

To me, I feel like if you love someone then you do the right thing by doing what you can to ensure their safety.

If someone is more concerned about their personal wants than the safety of those they are supposed to care about protecting, then it's not love.

Am I wrong?
