One question about the ending (spoilers)

When he saved her, it was in 1972. The last scene is probably 2014, 42 years later. Some kind of time warp thing. Lol

The ending was a bit confusing, wasn't it?

This is the way I understood it:

For a short time, through the magic of Purgatorydom, 1972 and 2014ish overlapped; that's why Edgar and Doris were able to travel back and forth between them. Edgar hangs himself from a tree in Doris' yard in that overlapping time. One of her daughters sees it in 1972, but it then disappears from her view. (Remember, she looks up, puzzled, and asks her mother what's going on, but then sits down calmly as though the scene was gone.)

Because of the time overlap, Edgar has also hanged himself in the present. When we see Maylon bringing flowers, it's a few years after he committed suicide. Remember, Doris says "is it another year already?" Maylon is bringing flowers to the site of his death, which strikes me as an odd thing to do with a suicide, but whatever. Her hairstyle is different and she's better dressed, which is supposed to be another clue that some time has passed since the events of the movie.

Exactly what Doris knows isn't 100% clear, although the fact that she remembers Edgar's last words and that she still has the tattoo suggests that she lived her life from 1972 onward with full knowledge of what had happened. That's kind of a freaky thing to live with, although I guess it would keep you towing the straight and narrow. She lived all those years knowing what would happen, and then one day, it did - Edgar hanged himself in her yard as the events of past and present finally coincide.

Or, anyway, that's my theory.

Doris lived the intervening years until Edgar's story takes place. He lived, and died, much later, but whatever powers there be allowed him to intercede and take her place.

This is straight-up fantasy, nothing of science about it. Doris was granted a reprieve thanks to Edgar's mercy and her own repentance.

So in Edgar's story, his death still takes place whenever it originally had. Doris may remember it as it really happened, but no one else living does, because no one else alive was in their relatively mild circle of hell with them.

The way I saw it was Doris' suicide merged with his timeline, so when he killed himself the Old Doris was the one who saw him hang himself, but in reality it was a merge of timelines.

someone had to die in her timeline(in the 70s), he took her place because he realized he wasn't a good man. in doing so it looped doris' day for her, without her actually being in it, therefore her life continued in the 70s until present day where she meets maylon and gogan.
