That's what I meant to say. She's not fully on-board, but she's dealing with it as best as she can. I think the most telling part was the line "We've come this far... what's one more?" or something along those lines. Skyler has reached a pretty dark place, as has pretty much every other character in this show (besides maybe Walt Jr).
I thought Anna Gunn summed it up the best on a recent podcast-- that at this point Skyler realizes she's already damned, so it doesn't much matter what they do anymore.
