Most Helpful Guy
Why not keep her as a roommate? Is she dangerous or otherwise unacceptable? I see two problems here, not one, the first is her wellbeing and the second is your relationship status. Honestly it doesn't really matter what your status is because once she goes back to Ohio she can easily move on as you're miles away. So that's not an issue; what is the issue is her current wellbeing I guess, but you can bar her from hanging out with you and just make it into a professional arrangement.
