I would be very careful if I were you. She sounds manipulative. She may have hired a family law attorney who may have told her that because she moved out of the home she essentially abandoned you and/or your son. Make sure that you go meet with an experienced family law attorney as soon as possible. The earlier you can get help with this the less damage it will have on your life long term. Can you imagine if she was to withhold your son away from you as well??
