All Over Again: Sequel to Terminal [Official] - Completed

I've read somewhere that the length of time a person should be able to move on from a "break up" is 1/3 of the time that the couple was together. But what does "together" mean?

Is it the time when you start having feelings for that person?
Is it just the time when you start being with that person?

What if the person was forcefully taken away?
What if the person never cared?
Does science or society set up any rules for those kinds of situation?

When is it okay to care for someone again?
When is it okay to fall in love without the guilt?
When is it okay to be with someone again?
When is it okay to find solace in someone else?
When is it okay to be okay?

This is what happened after the Terminal
This is the continuation of life.
