I left a few sentences out.

I'm posting them now. I just would like to know if the word choice is correct.

1)Before her mother died, she had promised (to her) that she would keep the house (the home?) together as long as she could.
2)She is no longer (a) child.
While she is waiting for the time to leave, memories from her past come before her.
3)She is determined to escape from her unhappy life with her new fiancè, though her father has forbidden her to see him.
4) She imagines how people at work would react at her elopment (???) with Mark.
5) She believes that once married to Mark, she could lead a succssful life abd be treated with respect.
There is a home waiting for her in Buenos Aires.
6) Her father doesn't agree on her relationship with Frank so she decides not to tell him anything about her plan to leave home.
7) She is torn between her determination to leave and break the chain with her past and the promise she made to her mum that she would keep the house together (on her mother's death).
8) When he invites her to leave she gets the impression he will drown her and eventually decides not to leave.
She knew he would be the only one who could free her (set her free?) from her unahappy live full of (?) self-sacrife.
9) She has given (laid down/sacrificed) her entire life for the sake of her family. Her cultural and social traditions prevent her from leaving.

1) Before her mother died, she had promised that she would keep the house together as long as she could.

"her" and "she" -- not the mother, right?

2) She is no longer a child. While she is waiting for the time to leave, memories from her past come before her.

3) She is determined to escape from her unhappy life with her new fiancè, even though her father has forbidden her to see him.

4) She imagines how people at work would react if she eloped with Mark.

5) She believes that, once married to Mark, she could lead a successful life and be treated with respect. There is a home waiting for her in Buenos Aires.

6) Her father doesn't agree with her relationship with Frank, so she decides not to tell him anything about her plan to leave home.

7) She is torn between her determination to leave, breaking the chains of her past, and the promise she made to her mum that she would keep the house together.

8) When he invites her to leave, she gets the impression he will drown her (<~~I don't understand this) and eventually decides not to leave.
She knew he would be the only one who could free her from her unhappy life full of self-sacrifice.

9) She has sacrificed her entire life for the sake of her family. Her cultural and social traditions prevent her from leaving.

Again, be sure to compare VERY carefully to catch everything, including commas, word choice, and spelling.
