Timeline and Summary

Eustacia is very miserable living on Egdon Heath with her grandfather.
Her ex-boyfriend, Damon Wildeve, nearly elopes with another woman.
But he has second thoughts and tries to win Eustacia back.
Eustacia is kind of receptive, but she's warned away from him by Diggory Venn.
Then Eustacia learns that Clym Yeobright is coming home from Paris.
She quickly falls for Clym instead and arranges to meet him by disguising herself and performing in a play.
Eustacia eventually meets Clym face-to-face and the two fall in love.
She marries Clym and hopes he'll take her back to Paris.
Eustacia doesn't get along with Clym's mother and the two have a huge argument.
The newlyweds live in a small cottage and Eustacia is devastated when Clym goes practically blind.
With her marriage falling apart, Eustacia starts growing closer to Damon Wildeve once again, who is now married to that other woman.
Damon visits Eustacia one day, but Mrs. Yeobright shows up too.
Eustacia doesn't let her in, thinking that Clym will get the door instead.
Clym doesn't, though, and Mrs. Yeobright dies later that day. Eustacia feels awful about the situation.
She doesn't tell Clym anything about it, but he eventually finds out what Eustacia did on his own.
The two have a huge argument and Eustacia leaves him.
Eustacia gets increasingly depressed and suicidal.
She continues to speak to Damon and agrees to run off to Paris with him.
The night the two try to leave, a huge storm arrives and both Damon and Eustacia drown.
