@eldersis and @Oversharingnamechanged both your stories are so upsetting to read.
OP, I actually feel very sorry for you, married to someone who would sulk at such a legitimate concern about his daughters safety.
You are married to a moron.
I definitely wouldn't be leaving them with your inlaws, not with an open house situation.
I have always been so fussy about who my children were with, and in particular about who they might be left with, luckily my husband would be absolutely on the same page.
My thinking was/is, here we are as parents, trying to do the very best we can with them every single day, their sleep, nutrition, education, provide a calm happy home, make the feel valued, loved, cherished, give them opportunities for sports, music, you name it.
Bending over backwards to give them the best start in life.
The truth is that that every bit of a happy loving home and childhood can absolutely be undone by allowing your child to be exposed to these bastards.
Childhoods are utterly destroyed by them, all that is remembered is the bewildered pain and confusion.
One friend had this happen to her by her fathers friend.
She never told her parents because she loved them too much and it would destroyed them.
She had MH, anxiety and depression for years until she told her friends the truth in her 30's.
The parents of children that this happen too are destroyed at knowing that they failed to protect their children.
I know it would have destroyed us, so we made the decision to be as proactive as we could.
They haven't led sheltered lives in the slightest but we were very fussy while they were young and were very clear about teaching them about body autonomy.
Your daughter needs you to be very firm on this, especially as her father is more concerned about his hurt feelings than his childs🙄.
Really unattractive in a man.
