Looking beyond being in relationships.

The point is really not about how to get a girl to be in relationship with. The real thing is to keep being in relationship. Maintaining it.

That's where natural bonding comes. That's where examinations and tests comes. 

2 people has to be in complimentary pages of their life, and pace has to be same , so that they can "grow together".

They're not gonna be what they used to be 20 years ago , or what will happen after 10 years from now on. The spice in both must be ever regenerative.

Thus "growing together" becomes important.
