The whole celeb world is shocked about Sushant Singh Rajput and Ankita Lokhande ending their 6 year old relationship as everyone including the fans were rather waiting for a big-fat wedding on the cards. Some rumors blamed Sushant's alleged closeness with actress Parineeti Chopra (they even clicked a cute selfie together) but as per a close friend of the couple it was Ankita’s insecurity that lead the fall out.

The friend told DNA that Ankita had become increasing controlling and possessive. She would call Sushat multiple times throughout the day when he would't be around. Sushant even asked her to give him some space. Ankita was behaving like this due to some of her past bad experiences. Eventually

their bond started breaking up slowly owing to Ankita's insecurities.
Whatever the reason may be, we are quite sad to know about their split(if its true!) :(
