Conditional and unconditional love

It seemed very unusual, that a girl who was considered unlucky (at least initially) by her own family before is so very well understood and loved by two people who came as a lover and the other as a husband--Yug and RB. I mean to say her own family forced her into a marriage and demanded the sacrifice of her love for YUG due to their own selfish reasons and ego. And these two persons who hardly knew her till her adulthood, are doing so much to see a glimpse of happiness in her life. Yug did everything possible to make her happy before and now RB knowing how she was forced into marriage, is trying to help her out and unite with her real happiness YUG. In yesterday's episode, Vrinda made RB and her mother realise that how much she loves YUG till now. And that how she accepted everything from childhood without questioning anything.

Here we can see how unconditonal the love of Yug and RB are, and how much conditionally Vrinda is being loved by her so called own people.

I might be wrong in my analysis as I haven't seen the serial from the beginning. I'ls feel nice if you all discuss your thoughts on this...
