I agree puppy. I think he is way to focused on her. He should be getting on with his plans of life without her.
He seems to hang on to anything positive she might say that gives him some hope or possibility of her changing her mind. He should not be interested in her plans at all IMO. Let her get on with it. He has to realise he has no control over this situation. There is not a gosh darned thing he can say that is going to make her stop and look up to the heavens and say .....My how foolish I have been !
The only thing that might make her slow up is detaching, disinterest and indifference. Thats a tall order but I see no other way. Nothing vengeful or ugly in this. Just real life consequenses for WAS
