Help (re-)identify a time travel SF short story

Some years ago here in CS, another Doper asked for help in identifying a story. Their wish was granted and I, a mere reader of the thread, looked it up and found it to be quite good. I have since lost the link to it and forgotten the name. A serach of the SDMB has proved fruitless as my search-fu sucks. So now I come back to the source, hoping to refresh my knowledge.

The story revolves around a man who has a brief affair with a girl who claims to be the daughter of a scientist who has invented time travel. She meets the man daily while he is on vacation and then disappears. There is a twisty, but sweet ending that I will not reveal now, unless it beceomes necessary to identify the story.

Can anyone help me, as that doper was helped in the past?

Got a unique word or phrase? “Time Travel” and “short story” don’t narrow it down very far.

I’m not familiar with the story, but I’ll guess the twist. Man says farewell to girlfriend, then goes off and 1) has a daughter and 2) invents time travel.

Cool and/or ew.

Nope. Goes home and eventually realizes that his wife is, in fact, the girl. She went farther back in time on her last trip so that she could meet him before he met her and they could be together.

More detail. He meets the girl while he is vacationing alone, at a cabin that he owns some significant distance from the city where he lives with his wife. They girl tells him about all the changes between the man’s time and the future in the area where they meet. She also says that time machine was illegal and that the government might find out at any time. He assumes that the government got to her or the machine stopped weorking when she stopped showing up.

The Journeyman was set in San Francisco. He has a wife, he time travels, he meets an ex-girlfriend while time travelling. She is probably a time traveller too.

Forever for a Hudson Bay Blanket by James Tiptree Jr has a cabin, a couple and a twist. Loulee 's dad didn’t invent time travel though.

I doubt anyone who read “Forever to a Hudson’s Bay Blanket” would describe it in the terms or the OP, and the description is nothing like the story.
