Devil's advice of
taking you out of the picture is sensible - seriously speaking,
you can do nothing more than what you had already
did. There is a limit on what you can help and what you
can't. (Listening ears, etc). You probably don't have the
heart/tact to send firm message across and making him think. He
probably have to get himself here and look at topic and go through
all the posts, because solutions CANNOT BE SPOONFED to him; if he
wants to solve it, he do it and not fear this, fear that and put it
aside:
This is what is needed to
be done - if he has to have something to tell him what to
do.
'G needs to learn to be a man and talk to them like a man
towards his women and learn to stop avoiding and putting problems
aside. He has been doing for so many years, is he still going to do
that? Trust me, with a good talk (essentially for their own good),
and a conclusion for their plight, he has to uphold the decision
and cannot do it half-heartedly. He has to leave the two woman
because none of them will be willing to see themselves losing to
the other party. His talk must be firm, taking lead, instead of
letting circumstance lead him (that's what he always do) and must
not fear that they will attempt sucide because this talk is
essentially a speech to clarify and present the issue on the table
and solve it like a mature love.
He has to reflect and ponder about the rational of his love
definition. He has to cease contact with them for min one year and
must cease doing 'things' that will indirectly create phantasmal
feelings for him. (sweet SMS, cards, emails, etc).'
Is he ready to leave them to pursue their next phrase of life?

Cheers
