Slightly disagree here. Second love need not be greater than first love imo. Your first love is special, coz its more naive, its idealistic the kind of love where you will lose yourself in it, more important than anything else, something like 'madly in love', this is the kind of love i associate with anupre. If you get betrayed in this love, then you can never love another with the same intensity, the same naivety, the same foolishness that you loved before. The second love is more mature, understanding, trusting. It is more practical, real and stable. 
Both anupre and prerish had their own equation. Anupres love kept changing forms but it always existed in someway or another. They didnt have to be together to love each other. Bajaj was the best husband for prerna. While anurag was her soulmate. Both men had their own importance in her life.
Haha,. That first love vibe na!! So beautiful and gungunta wala feelings. Love just happened between AnuPre.. Nokjhok, bato bato mein... Its the love anyone will want in their life, at least the romantic ones. Their love was love marriage type where PreRish love was arrange marriage typ. You know what I mean? Both of the loves have their own beauty... I love AnuPre, but I would like to fall in love in a mature way.. Like, with understanding, support, communications. Its because of age right now I guess. but when AnuPre fell for each other they were young and carefree.. Both were so much in love that bhondu Anu and Adarshbadi Prerna end up sleeping with each other just within afew days into their relationship. That carzily love some people worship. Its beautiful to fall for each other in this way.
But ekta's intension not at all was showing them like that. She wanted to create a painful lovestory n hence she wrote the whole prem darama n then prem death drama. Prem remained the most imp factors between them not to get over each other.
Oji main kehti hu.. Tussi wo kahawat toh suni hogi- 'do log jo payar mein the wo kabhi dost nahi banke reh nahi saktey.. Agar reh liye toh do hi baat ho sakti hain... Ya toh uein kabhi payar tha hi nahi ya phir unmein aj bhi payar hain.' ;) ;)
