I'm thinking more of the relationships Smita had in the United States in answering this question. Smita was free to date anyone, no matter his color, religion, education, or social status. She was free to have a casual, sexual relationship without damaging her marital prospects later in her life. Her relationships were up no her, not dictated by tradition or her father or brother. She could work outside the home and could end her relationship at any time.
Similarly, when she fell in love with Mohan, she did not need to talk to her father first. Her community in Brooklyn did not weigh in as to whether or not this was an acceptable match. Mohan and Smita will share the duties of raising Abru. Had Meena not chosen Abdul, her brother would have made the choice about who she would marry for her. Meena would have spent her days cooking, cleaning, and raising the children. I think Abdul really was a special man--his dreams for India included his wife, and he treated her as his equal more than his property.
