You can take her to court other than that there is nothing you can do. Stop fighting with her you are just fighting a losing battle. Maybe you son can do something to help you see him. I hope things work out in your favor soon. Take care.
How can I get even with an evil ex daughter in law who is brainwashing my grandson and turning him against me and also will not let me see him?
You got grandfather rights and if you got a good record you can go to court to win grandparents rights, to see your grand children
