Is there anyway you can reason with your wife? The fact is yorkies are generally hunters of low-lying creatures. So if there was a confrontation, the odds of the yorkie getting hurt are slim. But, I geuss whats done is done and I can only assume you've tried to reason with your wife already. But like someone said before, get rid of the snake because it bit someone is the same as getting rid of the yorkie if it bit someone. As many people have said yet again, try to get it to someone on this forum. Everyone here is knowledgeable and knows about the safety net that is, ball-pythons.net
