Is it ok to kick someone out of your home after they try to kill themself?

I have a weird sexual relationship with a housemate but he tried to kill himself 8 days ago (not because of me) and as a result has revealed his massive drug and alcohol addiction and unwillngness to accept and work through his many problems. My housemates asked him to leave because he was not willing to be completely sober and face these problems, which they said was a requirement of living in the house and being an adult. Is this the right thing to do or should we be more accepting of his issues and not alienate him from our lives? I kind of hate him but at the same time I still love him and the whole thing is consuming me.
