Maybe the fact that y'all had a good time on vacation made her afraid (subconsciously) that she was "going soft" on you, so she had to redraw the line in the sand with automatic weapons fire.
I think we all understand that you disrespected her wish by doing what you did. So okay, you may owe her an apology. BUT she vastly overreacted to what you did. Let's not overlook that. She could have easily moved your hand aside and said, "Remember, you agreed not to do that." But her reaction was way overboard. Kind of like The Pudding Incident.
To me, THAT'S the issue here. Not that you went against her wishes, but that she treated it like the Crime of the Century.
Yes, you disrespected her, but that doesn't make you a criminal.
And I think she also scared herself when she asked you to move out of the bedroom, and THAT'S why she was willing to talk later. Her righteousness depends on having you there to kick around. You are essential to her dance.
