Mrs. Linde and Mr. Krogstad were so in love at one time. However, Mrs. Linde was forced to marry another man because of her unfortunate circumstances. Having a sick mother and small brothers to care for, Mrs. Linde chose to marry a man who had financial stability. This broke Mr. Krogstad's heart.
As the story unfolds, Mrs. Linde, now a widow, comes back into town. She reunites with Krogstad. Krogstad and Mrs. Linde can communicate openly. This is a characteristic that is missing in the Helmer's relationship.
Mrs. Linde and Krogstad are completely honest with one another. This is a characteristic that is missing in the Helmer's marriage.
Mrs. Linde and Krogstad respect one another. This is a characteristic that is missing in the Helmer's relationship.
Torvald and Nora keep secrets. Well, at least Nora keeps secrets from Torvald. Torvald treats Nora as a child. He does not respect her intellect. On the contrary, Mrs. Linde and Krogstad see one another as equals. They are willing to stand side by side. Krogstad is not condescending as Torvald is to Nora.
Although Krogstad and Mrs. Linde have been through some difficult times, they are so fortunate to have found love one for the other once again. True love seems to be a missing element in the Helmer's relationship. No doubt, the Helmer's could take a lesson in love from Mr. Krogstad and Mrs. Linde:
At the end of the play, she and Krogstad are reconciled, but it is Mrs. Linde who decides that Nora and Torvald must face their problems. Thus, she stops Krogstad from retrieving his letter and moves the play toward its conclusion.
It is sad that the Helmer's do not have the genuine, loving relationship that Mr. Krogstad and Mrs. Linde have found in one another.
