I agree that there is something not quite right with this story. I think they trying to show that Yasmeen was so damaged by her experience with Geoff that it had affected her future relationships with any man. I dont want to say she is overreacting but she does seem to be getting into a terrible state when there is no immediate threat to her safety. Stu on the other hand could show more sensitivity and stop trying to make any contact with her when he sees how much it upsets her, or at least wait until he has some proof of his innocence.
