I need help-I am in love w/ someone who is severly bipolar?

I always suspected it, but found out last night w/ almost certainty that my ex fiance is. He is essentially at this point saying that b/c he has some level of self awareness that he knows he is not a good person and in order to 'save me' and for me to have a good life he is pushing me away and living a self destructive life w/ a low cl of people, he's not on drugs, but is drinking in excess and is doing whatever he can to push me away, even though it's killing him to do so. I am w/ a psychologist already, I want my fiance and my life back though and I don't want him to think he's trash like he thinks he is, he deserves so much more and we could be happy, like we were before this all started. What do i do?? He refuses to see a therapist.
