Agree it is best to just leave him and move forward.

But if I may...
a pet peeve...
Love/hate relationships are NOT a symptom or indicator of bipolar.

You will, however, find idealization/devaluation (ie. love/hate) in relationships among the symptoms of Borderline Personality Disorder: http://psychcentral.com/lib/2007/sym...lity-disorder/

(Some people have both.)

Thanks.
