Today is a complex world, and people need to learn more now than ever. My saying is “25 is the new 18”.
When I was 16 I started dating a girl, and we broke up when I was 30. When we were 30. We were good together, but we were with each other during times we should have been learning lessons.
There is good, and there is bad. Much of it has to do with their environment.
If you all dated for 14 years and you never married her, she should have dumped you at least 6 years before she did.
