No, having a 17 and 19-year-old in a relationship is not generally considered bad. In fact, many individuals in their late teenage years find themselves falling in love at younger ages. While it's natural to be cautious about getting too personal too soon, falling in love at 17 or 19 does not necessarily imply any serious issues. Instead, it highlights the natural and intense emotional bond that can form between young people who feel a strong connection.
