She also might use the time between sessions to think over your reactions and maybe change or modify her own feelings. After your taking the time to think about it more and her taking the time to think about it more, discussing it again at your next session you may come together better. Skipping the next session is not a very productive "punishment" for her and I wouldn't waste the session time--unless of course you're going to take stopdog's suggestion and drop her altogether. Which is entirely up to you.
