Any info on why these two broke up.

I know they're not that famous but few hyderabadi s are here so I thought so they might know something about them. To those who don't they both are kannada based Telugu serial actors(Nikhil&Kavya) who acted in gorintaku serial which was remaked as mehandi hai rachne wali in Hindi, They were in relationship nearly for 5-6 years. He entered biggboss Telugu stated he is single on stage, later discussed about his breakup lovestory multi times, Outside she shared a shady story when he talked about their relation even said he is being camera conscious, he won biggboss now he is being questioned about kavya in every interview.
