I know what you're going through. I've been through the same. I would advise that you don't try and hide your feelings from either of them. Anger and feelings of betrayal are normal. They are in a pretty horrible place too now, but in order to make the right decisions for themselves and for you they need to know how you feel and what you're thinking. Emotions are running hot and they will probably say and do things which they will regret. Your mother wants to run away, which is normal. I'm guessing, since you don't want to leave, that you like your Dad and the place where you live. It's good you told her you don't want to move. If you want her to listen, honesty (blunt honesty) is always best. My parents seperated: my Dad got remarried and my mother has jumped from relationship to relationship. It's been a very bumpy ride but I can say that I've come out of it all right and a much stronger person. Your parents still love you. Things might seem chaotic and dark right now, but I promise that it will get better.
