I am really shocked that your mother did this to your six year old child, my heart was in my mouth as I read your first post.
YOU WERE DEFENDING YOUR CHILD.
Any normal sound mother, would do the same. It must have been horrific to see your abusive parents doing the same thing to your precious child, as they have done to you as a child. Not only extremely triggering in every sense, but now your child has experienced first hand what you have been through.
Yes you might benefit from some gentle therapy that won't change who your parents are.
You are making the classic mistake of thinking somehow they will be different now they are grandparents. No, they are what they are. They are abusive bullies, and now it is your child's turn. You didn't have a fairytale childhood, and they are not magically going to turn into doting grandparents. Never ever, no matter how much you want to give your child lovely family connections, this happy family thing is never ever going to work in your case, unless you are prepared to let them hurt you and your child.
You may go through a grieving process for what you think your child has lost in not having very much/any contact with your dysfunctional family. You may at times wish for things to be different, for him to have GPs that love him and care for him but ultimately by shielding him from them you are giving him the best possible chance of being happy and well adjusted, and not continuing the cycle of abuse in your family.
The buck will need to stop with you.
So get some counselling, not for defending your child, but for the pain you have suffered a defenceless little girl.
Decide if these people are welcome in yours/your son's life.
Then you need to consider whether you have a marriage anymore, because quite frankly your husband's reaction is appalling. His child was assaulted by their grandparents, and he is taking their side??
It is astonishing that he feels that way given what happened to his child.
I would be distancing myself from him now, tell him the situation has made you reassess his ability to be a compassionate and loving husband and father. If he can not see the damage and pain your parents have caused you, if he can not recognise that his son is in similar danger and at risk from them, then he really isn't the person you thought he was. He needs to have your back in this.
Do you have some friends you can speak to about this? Or siblings? I am sorry you feel so lonely. I have had a similar life, and it is very difficult to deal with the fall out.
