Great job with college and work! That makes me feel better. Your age still makes the marriage more likely to end up in divorce I believe... I think that I have read that in the US early marriages on average yield more divorces. Try to see for yourself
http://www.census.gov/hhes/socdemo/marriage/. But even if it is eventually a divorce, it is still not a failure but a life experience. As long as you do not put the factors that lead to financial indepence on the back burner, it is totally OK to experiment with an early marriage.
