Ten years?
So what is your cut off; abused once, twice but the third time is the charm, one year, two years, therefore anything after that is somehow the kid’s responsibility, that they become responsible for their own abuse?
The kid was young and innocent when put into the care of a supposedly caring responsible adult. That adult abused him. That adult abused him over the course of many years. The kid, any kid in that situation might be lead to believe and conditioned that the abuse was somehow “normal” especially if no one came to his defense all those years.
At age 18 he finally realized that what happened to him was not at all “normal”. And somehow you still find blame in the victim? He’s “stupid “for being abused as a child? Really?
