I agree with Nibbles & Sheen, Rano did not steal Ranveer in any way shape or form. She married him because Raashi was sick and Rano wanted to make her happy. At first the thought of marrying her brother-in-law was unimaginable to her. she said this to Bani. but after five years of living in a house that Walia mansion has become and having no one support what the heck was she supposed to do, Ranveer was her only 'sahara' Its not like this is one sided either, Ranveer loves her as well.
No Raashi & Ranveer may not be divorced, but this is Ekta land, who would do anything the right way? Also, we are saying this because its 2007, what about the olden day kings who would have like 3 wives? I'm not saying thats right or wrong, but you have to take these serials for what they are worth.
Also the reason Rano & AD woudln't be a good pair is because they're going in two different directions in their lives, whereas Rano & Ranveer are both in the same boat.
