Lakshya absolutely took the right decision. We were fools to think that his love in unconditional (few will still disagree with me) and why should he care.
Poor guy learns that his beloved is taking drugs... He suspected that too earlier and made a great announcement to support his love and accept her... Dialogues make a man great, not actions.. Isn't it???
His bride-to-be is missing but why should he care... He came to get a bride, what if Swara is not there, he have Ragini as a backup... Dulhan hum le jaayenge, chaahe Ragini ho ya Swara, kya farak padta hai... And why should he care Swara is in which condition... She never supported him... She didn't trust him on the MMS scandal even when his family was against him... She didn't prove him innocent... Why should he care that Swara must be in which condition after her 'running away'...
All he should focus on is beend banunga ghodi chhaaddunga...
He should not fight the society for his love... Heck, even if Swara would have done the same in reverse scenario, but that should not apply for him...
