I think we should instead be teaching what to look for in a healthy long term relationship, doesnt matter the age. I got married at 22. Am happily married 5 years later and we are expecting our first. I was very selective with who I dated before my now husband and was very selective with him as well. I turned down many other guys who it would have been fun to date, but did not meet what I wanted in someone long term. Let's teach our kids the difference between someone you would want to date short term/just for fun and who to date long term.
