why rads couldnt love dev

Like all CB fans, I'm thrilled about the direction the story is going.
But the story has to remain consistent; Rads was constantly rebuking Dev to go after Vishaka, and willing to suffer endlessly for others.
The source of her love and devotion to Kanha is precisely this suffering - she has learned that she lives only for others, they are more important than her. Her love for Kanha, her duty, exists only in suffering.
She really loves Dev, but for her it doesn't make sense that happiness and duty could lie on the same path - if she wouldn't have loved Dev, she would maybe not have rejected him this much.
I hope the creatives keep this in mind for the story line; there should now be a period in which Dev shows Rads that happiness/enjoyment and duty are not mutually exclusive.

I hope Radhika will learn to 'live her life' along with letting others to live their lives happily(which she is already over doing now) in the coming episodes.
