One thing I don't understand is why they do not get divorced now? why does he still say she is his wife, when he wants to marry napur and wants to get tani married to someone else. Souldn't they do whats needed so that she is single again and can marry another guy, afterall Hindu people can only have 1 wife/husband right!?
Its completely understandable that he moved on in his life, as 8 yrs is a long time to be pinning for someone, if anything tani waiting for him without any connection is less realistic.
The only thing that was wrong on Anu is that when he re-met Tani he shoud have been clear about Napur straight away, you don't hide such HUGE news from your best friend :)
But then again its a serial, its not ment to make sense, just ment to be entertaining, which Tere Liye is for now.
