RICH talks about how a lot of times we date or get married to people who at first may be perfect for us, but as time goes on are quite the opposite. People need to understand that if they are in a relationship with someone for a long period of time, things are going to always be changing. They may have kids, they may change careers or move somewhere else, their religious or political views may change as well. People change and there is nothing you can do to change it.
