Betty loved Dan more than she lived herself. After giving her life to Dan so that he can be successful, with hopes one day she can begin to enjoy life. Yet, as it often happens, the successful man forgets the sacrifices that he allowed and insisted the wife take, without realizing that she's being used for a personal purpose that wasn't really love. Dan knew that Linda knew what she was going to get by cheating with him. Murder should not have happened, but I saw the hurt Betty had, she lost her youth to Dan and acted in an immature way because Dan didn't allow her to grow with him. He used her as a pretty young productive machine until got where he wanted to be and found a new Betty to start over again.
