Dev the spoilt brat due to his habits and pushing from an ever controlling wife married Geet, took dowry from her family, slept with Geet, and left her at the airport like she was nothing. He ruined Geet's innocence, making her accept the harsh reality of being an illegal cheated spouse and in reality an unmarried pregnant girl in a strong conservative society.
Dev the jerk is the ultimate cause for Geet having 2 attempts on her life, and estrangement from her family.
Now when Geet, a fallen woman (society's perspective) finally gets a second chance at life, who comes and ruins it? ...None other than Dev. And all this despite teh numerous times Meera told him to think before he acts.
Seriously I'd want to him to suffer in jail for life time imprisonment... for everything he did.
