Please read my posts on this thread. They might apply to your situation. Mothers program their children’s feelings, often without even knowing it.
I’ve seen mothers do it willingly, and others do it unwillingly (perhaps best stated as unknowingly). And of the ones who did it willingly, I’d break those into two categories: the mothers who did it willingly but not knowing the child had a need for a relationship with the father, and the mothers who did it knowing full well the child has a strong relationship with the father and was even emulating the good things from the father.
