when a father hurts his own child what does that say about his mental attitude.as the childs mother who also experienced his abuse in the past how can i deal with this situation mentally so as it does not stay with me in a negative way for too long. im having trouble understanding how he can say he does not remember doing these things. Also i have reported him for the abuse.
What would be the best way of making this man better and also the best way of helping my son trust other men in his life
It may be speculated why someone hurts their own child - because of a mental illness, if they abuse substances such as alcohol or illegal drugs, if they have an antisocial personality trait, because they had not learned proper parenting themselves, etc. The reasons can be many and it depends on each individual case.
As far as helping his son trust other men, he would have to do so in time and by being exposed to positive male role models. Depending on your son's age counseling may help too.
As far as rehabilitating the father, (this has to be a choice he makes and sticks with it and it takes time and progress is slow) In some cases like this one, the father never changes and will continue to abuse unless he is stopped by the law or the victim(s) move away.
