The Basic Assertions
These basic assertions may simplify your life.
Every relationship is unique
This means every single one. There might be common points, but that's only surface resemblance. Look, even the relationship between the same two people can change over a period of days, weeks, years (unless you're being held captive by a psychopath who whispers "don't ever change" in your ear every night). You'll simply be a lot happier when you start thinking: "It's just different."
Enjoy the differences. Enjoy the similarities.
Anyone has the right to form whatever relationships they wish
This is a lot more power than most people are comfortable with in a relationship, but most of the reluctance to accept this assertion stems from the idea that relationships are property, or that the other person might abuse this power.
As far as the "property" thing goes, maybe some people like it that way. Good for them. I'll pass.
Anyone afraid of having this power lorded over them should reconsider their choice of partners. They would also do well to master communication skills. Also, keep in mind that this -- as with all sorts of things in this little document -- is completely reversible. On one hand, you can all maintain a balance of terror. You can also maintain a balance of pleasure. Whatever you want.
These two assertions are very useful in dealing with jealousy and the fear of being replaced. The first helps reduce the fear of being replaced. The second suggests that different relationships might even complement each other, particularly if there is a perceived need.
Crazy, huh? Yeah, I thought so, too.
