Cool WW...
Sledge, what's with the hate? Is he a douche bag, probably. And so what if he fucked up his own life, are you effected by it? Maybe we should lay off the "water cooler" news a bit and stick with the stuff that matters to all of us directly. And as long as it is legal, whose place is it to judge them? Now assuming he wasn't doing anything to her before she was 18 there is nothing illegal about what THEY did.
I bet she does have daddy issues and I hope whatever happens she finds happiness. We all deserve it in our lives, unless your form of happiness is the downfall or destruction of others. Let the chips land where they may on this one, but if you don't like the way the game is going just get up and move to a different table.
