Firstly, if you want to give your marriage a second chance wouldn't you visit a counsellor or take a trip as a couple so that you can re-discover your bond etc. Why would you participate in a reality TV and that too BB which is a known madhouse where you are 24x7 under the watch of cameras, surrounded by strangers and could be possibly put in situations where you might end up being at loggerheads with each other?
And is the season going to conclude with Rubina winning and then Rubina Abhinav announcing that they are going to give each other another chance and thank BB for it all?
