I hear you, I didn't go to work today either, just couldn't (at least the holiday is an excuse but tomorrow is another day and we must face it). Do you think it is immaturity on her part or maybe she was just after money? Whatever the reason, what she did was WRONG. If she was unhappy and wanted to be with someone else she should have had the decency to tell you and end the marriage first. Stay strong, be calm. I think your going to a hotel was a good idea, to give yourself some safe space to be alone and let the emotions subside. Don't be humiliated to go back to your house, you have nothing to be ashamed of, she does. Remember to keep your cool, show her you are above this nonsense. Good luck.
