I’m so sorry this happened to you, I have been in a similar position.
It’s not your fault and you have no blame in this. Ignore the posters who don’t get this, they sound clueless.
It is a very common reaction that no one believes sexual abuse occurring within the family, it’s much easier for them to think there was some misunderstanding.
The truth is so heinous and disgusting, that no one wants to believe this kind of evil exists. Unfortunately it does, and doing it in plain sight is one of the tactics of these psychopaths.
Most women do have a freeze response, in shock, stunned disbelief, horror… you can’t believe it’s happening, let alone what to do about it, it does a number on the psyche and is very traumatic and damaging.
I was young and inexperienced, didn’t have children and the perpetrator wasn’t an in-law. No one believed me, it was I who was painted as a sick malicious liar (this also happens commonly in these situations), the abuser was a saint and not enough could be done for him. I got verbal and emotional abuse. Funnily enough, the punishment of me was coming from exclusively from the women of the family, as is happening here…. the self betrayal of deep ingrained misogyny .
My solution was the distance myself from the family and all those who disbelieved and unsettled my peace. Then, we’ll, what do you know, he carried on abusing and it happened to other family members eventually. Everyone finally saw him for the psychopath he was, but it took years.
In your position, I would report it to the police… for the sake of your grandBABY, this guy is very dangerous if he has already been so bold and to his mother in law in sight of his wife with his baby in your arms… just sickening.
We need to save this baby, your daughter is an adult who can make her own decisions.
My perpetrator was only stopped because each person reported him. To save and help future victims, mainly your grandchild, you must do the same, this individual is obviously no stranger to incest if he he’s evil enough to try this with you, a child would have no chance.
Please act, immediately. You will be taken seriously. The use of it will be that the next victim will be believed and something will be done!
