Oxford, you say you're a smart, educated man. What do you think? You detach by CHOOSING not to do things with her or interact with her in any other way than as a casual roommate. Nobody has a gun to her head. It's not like she's going to jump into your car or follow you if you decline to go to the gym with her. The problem here is you don't really want to stop interacting with her. You somehow want this drama. Think about that and OWN it.
