My wife and I are travelling LAX>SLC but are on separate itineraries. I depart tomorrow, she departs Friday. We are both on the same return flight on Sunday. I am Gold, she has no status.

I got upgraded to First on my Tuesday flight and it looks like I have requested an upgrade for Sunday's flight (at least according to what the itinerary shows me on delta.com). If I somehow get upgraded in advance for Sunday's flight, I assume there's no way for her to get upgraded with me? If so, how would I "un-request" an upgrade so that we don't end up sitting apart? (Of course if I do get upgraded it'll be my wife sitting in first )
