I was talking to my sister yesterday and she mentioned that she'd been 'reconnecting' with an old friend via facebook; my YF's brother, who she went out with briefly.

Well, conversation ended up between them in the direction of "so why did your parents (mom and stepdad) split up?", which I also knew, but not the reason.
It turns out his stepdad was incarcerated for molesting him and, presumably, his brother when they were younger (he's 18, my YF is 16). That would be around the same time we were living there. I say 'presumably' because: 1.my sister didn't press the subject further, and he said 'molested US'. 2.My YF's brother always hated his stepdad. So even if he was molested and my YF wasn't he'd most likely still inculpate him for it. 3.I haven't talked to my YF since before all this came to light...

But even with the possibility that he wasn't I found myself thinking about it ALL day long.
I went from pure surprise to quite an intense anger, thinking that the person I loved so much could have been abused in such a way. Also because whenever I ran into temptation with him, I always did the 'right thing' because his mental/spiritual well-being was so sacred and inviolable to me that it was all that mattered; while someone else was so careless & selfish to possibly psychologically 'screw him up' so to speak. And I'm also a bit down that (if it really DID happen) my YF never felt the need or safety to tell me.

It's a really weird feeling when you're on the victim's side. I gotta say, at least I sort of understand better what anti-paedophile groups must feel, and the laws that go with that; not enough to condone the extremes by a long shot, but at least I see the sentiment behind it.

Still, I gotta find out for sure what happened. All I know is that their stepdad won't get out for 3 years or so, but I don't know the charge(s), and my YF's brother could've exaggerated the story.
