For months, now the ex has been sending emails that are both derogatory and verbally abusive. Now the ex is telling the children (when on access) that I am basically stupid, and am mentally not all there. (I will add that I have a degree and am working on an MBA). We have limited contact and comments are unfounded and nothing more than an effort to have the children turn against me and live with the ex. I can't afford to go to family court. Is there anything I can do? This is in no way in the best interest of the children.
