My first boyfriend was at 21, was married 4 months later(no babies) lasted 25 years, divorced-yet stayed friends.
Married second time, (same year as divorced), still married going on 5 years now.
Been married longer than single. Would have called anyone crazy and laughed in their face had they told me this before age 21.
Never say never, nor forever, because things CAN change if you allow it.
