Now comes the hard part for you - being patient and letting him come to you. I can't imagine how difficult that would be, but it is critical for you to figure out how to do it.
He is going to need far more than a few days or a week Ali, come on you know that. Use your session, don't fall through impatience at the last hurdle. Phone him about viewing, be chatty, but not too much, keep it light. Let him suggest to meet or not. No pressure, wistful sighs or any hint that you are waiting for him to come back now he is not with Helen. He needs time to grieve this relationship however ill suited it was, it happened and he obviously felt something for her. Put all your creativity into art work and not imaginings, the P word and then some.
