The Awakening

I had a different view of women that time after reading The Awakening. As post-Victorian women, they were not expected to be "social" and they were required to be good wives and mothers and husbands' helpers. However, Edna refused to live this kind of life. She learned to swim; she did arts; she found her own love. But unfortunately, Edna were neither brave enough to be a "outsider" nor would she like to continue the old life. She suffered a lot and when she found even Robert did not understand her, she was completely awakening. That society was not for women to be active or to choose their own lifestyle. So, at the end of the book, Edna chose to suicide while she was completely freed from the constrained society.
Question: Did the Leonce found out the relationship between Robert and Edna?
