Later in 2012 my friend is moved to Mumbai and asked her to come to Mumbai to live. She SId many excuses that includes her brother marriage. She didn't invited him to her brother marriage or ear boring ceremony which commonly held in south India. Later in 2013, this guy attracted by another girl and got silently married her and living in Mumbai. In 2014, when he moved to bangalore, he himself informed her about his new life and asked her to give divorce.
