My girlfriend refuses to quit smoking cigarettes and I’m worried about her health because she’s always coughing. She always smells like an ashtray. She used to go it and smoke in the cold, but she made me feel bad so I let her smoke in my apartment over winter break when it was snowing. Now she chain smokes in my studio apartment constantly whenever she’s not T the bar and now my tiny apartment reeks.

What do I do now?
