Step-by-step explanation:
The story is quite short, I'd recommend reading it. I had to do a Marxist analysis on it which is the only reason I can really help you out.
1. Having a high, aristocratic lifestyle full is what motivates Loisel to do the things she does.
2. She believes that because of her status as a woman born to clerks, she wouldn't be able to marry into the lifestyle she desires so she practically settles for her husband
3. (Personal opinion) I believe it was smart of her to marry her husband as she would've had a much harder life as a spinster in her time and even harder to live with a lower class family that wouldn't be able to provide for her in her later years. At least with a husband she was able to provide for herself and live a somewhat comfortable life up till this point
4. She became stronger and more humble, she no longer cared to keep up with the appearance of a distinguished, high class aristocratic woman and decided to be the kind of woman who wasn't afraid to be loud and get her hands dirty in order to pay off her bills.
5. (I don't know what version of the play you have, but this is the line from a version online) "How foolish you are!" her husband cried. "Go look up your friend, Madame Forestier, and ask her to lend you some jewels. You're intimate enough with her to do that.", he finds her obsession with status and needing to look the part of a beautiful, famed woman somewhat ridiculous and he loses her temper with her as not only did he give her 400 francs for a nice dress but now she was demanding something he clearly can not afford as well.
6. (Personal opinion) Heroic, she knew she owed a great debt to her friend so she put her head down and worked hard to repay what she thought she owed. In hindsight it may seem foolish as it turns out the necklace was worth squat but from her point of view she did what was what she needed to do.
7. (Personal opinion) I believe the story is teaching us that money and status are not worth chasing. If Loisel had simply gone in her gown at home, flowers for 10 francs she would've never had to work as hard as she did. If she hasn't asked for expensive jewelry, losing her own instead then she would've been fine financially and all would be well in her life. In fact is she wasn't so desperate to be at a party with the governor her husband wouldn't have worked as hard as he did to acquire that ticket to the ball so she could have her magical night. Every expensive choice she made could've been avoided and she could still live her comfortable life instead she chose to chase fame and fortune.
