He left Ragini. He put the wishes of a friend ahead of his relationship with his wife.
The adopted baby, born to his friend, was more important than staying and raising his own kids.
He seemed not to find any way of convincing Ragini of the truth and winning her trust.
He chose to leave. Such a stupid MU! (The writers continue to insult the viewers' intelligence)
And yet, 15 years later, he behaves like there was no divorce. How can Ragini be possibly married to another man? How could she? His Ragini! "You know I am so possessive about you. You know I can't bear to see you with another man" Oh please give us a break! No one believes you Neil.
Ragini could have married and divorced several times in those 15 years! Or had untold
one-night-stands, or dated every man in the hospital where she works, or got piercings everywhere, or listened to really loud rap music every night and pissed off the Society, or sold her house and moved to Mexico...
She could have even moved to the moon, you wouldn't have known or cared. You never called her in 15 years!
Oh yes, you didn't waste any time being alone while living in NYC. You had many relationships, - you were certainly not celibate!
So why this sudden care and ownership of an ex-wife?
If Neil always cared, then why did he stay away?
The 15-year gap makes it very difficult to buy this story.
The writers messed up.
