the fact that bajaj put his wife wishes above his own personal vendetta says something big. Especially when they got married and they barely said anything to one another. If he wanted he could have gone back on that promise after marrying her. But he put her above him. The same when she wanted to take care of basu after the accident. He allowed her to as well as her going to the hospital despite warning her mohini will insult her. Again because she wanted it he went along with it. That is respect. True respect. Especially for someone you don't know well.
Basu loves prerna but when has he ever put her first? People want to nick pick at bajaj and call her bad because of how they marriage came to be. But the biggest insult was when basu chose his family business over prerna. Knowing that he wronged her badly he still chose his business over her. That showed when it comes to saving his family he won't hesitate to sacrifice her. Bajaj on the other hand puts his family in their place. He chose prerna over them. Especially after knowing taanvi and aunt for so long.
The problem was after seeing prerna with a different man then basu got all riled up and did damage to another marriage. He couldn't bear to see bajaj have what he what but when he ditched prerna to marry komo everything was ok then. Lol
That is the main thing about RB he always choose prena above all.....
