It's easy to point fingers in all kinds of directions in a case like this. But I know that I did the tenth dive of my life to 130 feet in Molokini crater, on an Al80, because my guide was a PADI instructor and I trusted him. I HAD done my AOW, but that still doesn't change the fact that I was an inexperienced diver, too deep on too little gas. It all came out fine, as it so often does.
If the plan was to air-share to extend gas, it should have been done when your wife had plenty in her tank to do her own ascent. Taking her away from the line when she was ALREADY low on gas was a bad decision. Buddying up with a new diver when the DM was already responsible for a group is a dubious decision, too -- although I saw DMs do this in the South Pacific, and share gas early in the dive (with a long hose) and it worked OK.
I have no problem with a spouse pair splitting up for a dive. My husband and I have probably done as many dives where we weren't buddies as we have dives where we were. But I'm not sure WHY you guys split up for this particular dive, especially if you knew the DM buddying up for your wife was also responsible for the whole group.
If a dive op's strategy is that the first person low on gas makes the whole group ascend, I'm not using that dive op.
It was a strategic error in several directions, but in the end, my guess is everybody involved learned something from it, and no one was hurt. And it's a good idea to read Bob's gas management article
