I really hope you can reach a resolution. If you feel he is making his decision for the 'wrong' reasons (not reasons based on judgement of a situation, but on emotion - fear denial, etc) then I think that changes he situation a bit too. I really think mediation (not someone saying what you should do, but rather someone working with you both to reach a compromise) is your best shot of a resolution. Relationships Australia do this kind of mediation.
