Actor Ranvir Shorey, who recently announced his separation from actress-wife Konkona Sensharma after five years together, says he still believes in the institution of marriage. Shorey said he blamed himself for the breakdown of his relationship and not the institution. “I do believe in the institution of marriage… I don’t blame it, I blame myself (for the split). I don’t think institution of marriage has anything to do it,” Shorey told reporters here at the promotional event of his upcoming film Titli.
