There is an expression that goes “When there is a divorce – they don’t go handing out sweets”. Meaning that there are never parties, or compliments but usually bitter accusations and terrible allegations, one against the other.
I love coffee: If you have been the victim of parental alienation you could always try to investigate the situation objectively as an adult, wherein sometimes the mother tries to paint the father in a bad light, and seemingly “protects the children from him”. Where as it may be far from the truth.
Always give the other side a chance to explain why they broke up and hear out your father.
Google Parental Alienation.
I should know – I was a victim of it.
