Great answer from the Dr. on a difficult issue, as usual.
He tried to be patient and kind and supporting, and this went nowhere. He deserves to be with someone whom he likes and enjoys (BTW, I would say the same with genders reversed).
And to the ones complaining "Love should not be based on looks!", I call BS: almost no one would choose a partner without feeling physical attraction - no men and no women either. So don't fool yourself.
Is it "conditional love"? Yes, but any adult relationship IS based on conditional love - at least in part. We choose a partner based on who s/he is AND what s/he does (and women are even pickier than men about this); and if s/he becomes very different, the relationship doesn't work anymore.
