Is breakup a fashion in Bollywood?

Bollywood is also known for relationship and breakups of its actors. While some relationship turn into strong relationship and result in marriages, others end into breakups. Again, some breakups turn into sour relationship, whereas many a continue into friendship. Take the case of the B Town`s Dabangg star Salman Khan who has a long list of relationships and breakups, yet his breakups don`t into end into total breakups. Salman continues to be friendly with all his past love interests. Salman says he doesn`t cry for his past love with Somi Ali, Sangeeta Bijlani, Aishwarya Rai and last of all Katrina Kaif. He has no quarrel with any of them and tries to be in professional as wellas personal touch with them. It doesn`t matter to Salman if Katrina that Kaif of late has grown relations with Ranbir Kapoor. That`s why Katrina can easily share screen or platform with either Salman or Ranbir. Similar are the relations between Deepika Padukone and Ranbir Kapoor. Still, Deepika has the best of relations with Ranbir though she has been reportedly going to marry Ranveer Singh. On the other hand, we find that Bipasha Basu who had once strong relationship with John Abraham  is no longer friendly or cordial with John.
