Hey Blackwolf. Read your OP. It sounds as if the text about being at tge KH could have been mine.
I've been faded now for 17mnths. Dont5miss any of it. My situation is different from you in that I'm not dependent on parents. I don't want to patronise you, sufficient to say I remember what it was like to live in a strict non-jw household.
People can't trace internet history via a router. Your dad is just planting seeds to further emasculate you. It's a tried & tested weapon. They need your device. If you clear your history, then not possible, unless experts take it in. The only thing he can do is monitor you live. He'd have to sit there & watch numbers whizzing past him. Then he'd have to know what they all mean. Unless I've missed parental snooping technology advances. In which case, I stand corrected.
Please please just hang fire. Time does pass slowly when your young. Keep visiting or posting. We're routing for you buddy.
