There be double standards here:
Another recurring theme in Moffat’s episodes is that he really likes to trap his women: River in the computer, Reinette on the “slow path”, Amy in the past. Sure, they get to live out the rest of their lives (or their consciousness, as is River’s case), but they are forever gone, and have no way of ever coming back. They will never see the Doctor again, and the way that these women have expressed themselves, it seems like a fate worse than death.
And Rose gets trapped in a parallel universe and Donna’s mind gets raped so she can never see him or even know about him ever again, “like a fate worse than death.” But you don’t see Miss Alice Marie talking about that, now do you?
So The Doctor honors River by uploading her to a computer in a tradition mirroring that of dead Time Lords getting put into The Matrix on Gallifrey, but River is “trapped.”
Reinette somehow living out her life as she did historically is also being “trapped.”
And Amy and Rory…yes, they did get trapped in the past and were never able to see The Doctor again. But it was no worse than Rose getting trapped in the parallel universe TWICE, the second time with her very own meta crisis. And, in fact, their fate is a much happier one than Donna’s, who Wilf basically admits to The Doctor is settling (and is so very sad but doesn’t know why), so she gets married to Shaun who is nice enough because she can’t remember anything better.
Let me just reiterate this, too:
They will never see the Doctor again, and the way that these women have expressed themselves, it seems like a fate worse than death.
And of all the examples stated, only Rose and Donna are the ones who have said they planned to travel with The Doctor forever. (Rose actually describes getting stuck in the parallel universe, away from The Doctor, in “Doomsday” as “This is the story of how I died.”)
Meanwhile, Amy, Rory, and River all made lives outside of The Doctor. River told him point blank that there would be boundaries with their traveling together, despite being married.
