I think it was supposed to be a gradual thing. She said his art never took off, and she threw herself more and more into work. It sounded like they just gradually drifted apart. Ten years DOES seem like a long time though, I'll agree.
I liked that she tried to use her future knowledge and it didn't work out perfectly...its such a cliche that if one could just go back in time, that they could use their future knowledge and things would work out perfectly for them. I'd like to think if I woke up in 1995 that I'd get hard at work inventing Google, or Amazon, or Netflix or something...but I probably wouldn't, lol.
And the criticism about not mentioning/talking about 9/11...what would she even say? "Oh yeah, in six years or so, terrorists fly planes into the Twin Towers. We should totally stop that!" she'd be written off as a lunatic. There'd sadly be no way she could prove it, Lolly only really believed her when the purple Docs came into her life.
