I don't think he should be 'slagging her off' but there is no anger and any innocent person in the same position, would feel anger and I know it's not because he doesn't have it in him to be angry (before someone says that.
No I agree - and as she claims he was dumping her it cant be that he loved her deeply.
He was begging her to tell the truth - but did not seem to be angry .
If he was guilty and she dobbed him in you would still think he would be angry
if he was innocent and she dobbed him in you still think he would be angry
So I wonder what the answer is?
