It's interesting, when the woman in this story are finding their own independence, such as Alma defying Ennis, working, making choices in her life. Lureen running a business, even Cassie wanting to go to nursing school. These woman are looking outside the traditional role. They may have various reasons why but they made changes.
Ennis and Jack couldn't, wouldn't, or didn't know how to move on, or grow in their relationship, or even the way they were themselves living their lives. How could they? When neither of them couldn't even come to terms of who and what they were. Two men who in love with each other. Even as late as 1983, they still couldn't come to terms.
The woman emerge stronger by choice, need, or circumstance. But fear of change and of their love for each other kept Jack and Ennis stuck in their limited world.
