I just wonder what kind of "failure" is Peter facing. The best I can guess?, maybe Aunt May's death. I mean, OMD is undone, that would restore the Spider-Marriage, but it would also surely involve Aunt May's death.
"Spider-Man No More" had a similar plot because Peter was too depressed after finding out he was clone and Ben was the original. (That was fixed later). Anyway, no doubt Peter will return as the Amazing Spider-Man by #900.
