This morning WW threw a tantrum. What should I do?

So, kids sitting at table eating breakfast, WW heads out the house door and turns to me and says, "don't need to move the car.. I am taking it today". I reply in a firm voice, "no, I prefer you not take the car" and follow her out the door. She jumps into the car. I told her I don't know where she goes when she leaves the house (over a year ago she told me she had early work meetings but learned via cell GPS she was going over to OM house which she confirmed.. PA) and I don't intrude on her privacy. She gave me a funny look and said "now you keeping your phone with you and are placing it face down" ($h!t that's what she does.. I just chose to not let that bother me anymore.. I am working on me). So.. I get down to her eye level and calmly tell her, "I am here for the kids.. and I need to do what's right for the kids and me" (I can't pull her out of the car so I walk away back into house and close the entry door.. she follows saying.. I just wanted to see your reaction.. opens the entry door and throws the car key fob into the house.. (my boys see her throw the keys.. clearly a tantrum).
