You've been through a lot. You're disoriented and pissed. Fair enough. I won't hold it against you for being a little grumpy. I will hold it against you if you keep talking to her that way. That demon doesn't have anything to do with what happened to you back home. Furthermore, she's my wife. You do not want to insult a man's wife in front of him. It's just stupid.
I can answer any questions that you have, so long as you promise to cut the attitude with Ruby.
