Yes this behavior have a name

This is a 10 year old situation I have thought many things about it, that she was just scare of  Willmael not loving her like she wanted him to (a mother) not for what she is his grandmother, other moments I have thought it was to work to her advantage because her husband fall in love with little kids for example his ex-wife use baby sit a little boy they toke him to vacation to Puerto Rico just because, she had study him for years before even married him she knew how to milk him out just because he love kids he was her best friend husband, some other times i think because i told her she created the monster her son was and she make him so dysfunctional to society she did a poor job as a mother to her own kids and she wanted to re-do her wrongs but the ultimate reason she is an evil narcissistic person who rejoice in taking over peoples lives with any remorse.When  I started researching if the intimidation she have been doing to my son  is a kind of child abuse and how can i prove it to the courts or the department of social services to make her stop I discover what she was doing to us Parental.Alienation.Syndrome and my son have all the key behaviors he acts totally different when his grandmother is close him when he was with me play had fun and kiss and hug with out hesitation and then ask for secrecy or not to tell her he was good with me he have depression anxiety and behaviors problems in school and of couse after meds he atarted to behave more better but she claims is because he have not see me (BULL). She blame it on me of course she said i was the worse mother to my older boys I say go head any body ask them I was the best mother and father I cut be in my situation but who can judge with her own story to tell right, mother of three but who are her kids today go head ask her. Anybody can make mistakes but to recognize it and make changes not everyone. The courts in Springfield Massachusetts have fail my son tremendously, they have fail to make it fair is who ever can pay the best lawyer or who can lie better to the court who can make false accusations towards the other parent then they don't even consider a lie detector test as evidence but they will take false testimony from a person it have never meet me before. The laws in the court system  needs to change the have cracks and children like my son Willmael are falling between then children are being hurt by this form of child abuse and they just look away and just swiping it under the carpet make it believe because this have not yet been prove as the psychological society or court systems  is not there but so those air we don't see it but is there and we need right is maybe not a syndrome is more like a behavior cause by an narcissistic parent or guardian abuse who is going to be the brave source of enlightenment who will help this kids.
