You need to just ask her.
I don't want to come off as unnecessarily harsh on you. My reactions have been directed more at the pile-on that seemed to happen at the beginning of this conversation.
There are other possible explanations for the things you've observed, it's important to remain open to them, I think. It's a particularly difficult situation because of your recent argument and you probably feel a little like you're walking on eggshells. But it's important to air your suspicions and get past it, otherwise they will persist in haunting you every time you 'notice something' about your wife, know what I mean?
