When you ignore people and issues with brinkmanship as your policy you aren’t anymore safe and things aren’t anymore less likely to end in the worst possible scenario.
I don’t care.
I’m not going to discuss this with you.
You can do whatever you like.
All great ways to show ya either don’t care (you said it) or you’re prepared to love everything by taking it all to the brink of disaster.
Living with the person you slept with to get back at me is also a whole new ball game. I can’t see any future with me in it when I have to be reminded of what happened because of your choices of roommate.
