<human>: Can you succinctly summarize the text in 1-3 sentences?

[OP here](

Thanks to those who gave advice. The situation handled itself oddly enough without me being involved. 

The roommate has basically "broken up" with my wife and their friendship is dead. It was a tough couple of weeks for my wife because she takes rejection pretty hard. But! that's helped my wife remove the rose-tinted glasses and recognize the warning signs in her roommate's behavior. 

I visit every weekend and have not seen roomie once in the last 4 weeks since posting, but she's apparently still smoking 2-3 times a week at least and hanging out outside of the apartment. 

They still have until July living together, but my wife has decided not to move while the roomie has decided to leave and get a dog of her own. My wife's plan is to be the mentor/sponsor for 2 first year students in the program, which is awesome.
<bot>: Roomie "broke up" with my wife and is headed out on her own. Wife was sad but is better, and will "mentor" 2 first years in her program next year.
