Hey, at least it's not a redo of the twincest letter from days of yore.

These two became stepbrothers at ten, not two. Nobody would reasonably say that they're only "technically" stepbrothers, because they have clear and distinct childhood memories from before they even met. OP needs to close that door and pretend she never opened it.

With that said, I think it's entirely possible that OP and Hubby *were* bad parents if, as she says, she mostly focused on the little kids and left the older two to raise themselves the rest of the way. Not that that has anything to do with anything.
