My ex got engaged, is she gone forever or did I lose true love

Hello sir, I’m Rajat, born 9 April 1993 at 9:00 AM in Nagpur. I dated Pooja (DOB 27 June 1995) for 5 years. We broke up because I wasn’t ready for marriage. She got engaged last month to someone else. I’ve never felt this kind of regret. Is she gone forever from my chart?
