Whether she wears the rings when she goes out with friends, I don't know. But it is standard advice to take off jewelry before going to the hospital. Things can get lost or stolen there. And Dsh is right, you are obsessing. Try to keep in mind that you know she lies to you. So asking questions and hanging on the answers does you no good at all. You may as well buy a ouiji ball. The answers will be about as accurate.
You need to ignore her as much as possible during the next two weeks. You have to get used to being a single father. Your son needs to be your focus. Your wife may come back, or she may not. But keep in mind, she will only come back if she thinks it is good for her. She is not concerned about what is good for you. If she does come back, you need lots of changes in her, or this pattern will just repeat.
I am NOT advising you to ask her to change. You are nowhere near ready for that conversation. What I am saying is, you need to get it through your brain that she is not good for you now. You don't need someone who treats you the way she treats you for a wife. As things stand, you are indeed better off without her. You didn't need the abuse last night when you asked a question and got a lie for an answer. If she wants you to be nice to her, like taking care of her when she is sick, then she needs to be nice to you. Not just when she needs you. She needs to find a way to be nice to you, or she needs to call someone else in an emergency. You will not get respect unless you demand respect.
In the meantime, let things lie. Don't start arguments; don't pursue her. Have as little to do with her as possible.
