Somewhere it is considered adequate to meet / communicate / go to the cinema / accept gifts, etc. - from other people.

There are also those couples where it is not meant monogamy, but polygamy.

There can be many reasons for this format of relations. Benefit: joint rental housing, separation of life, etc. And someone simply does not want to miss the opportunity to enjoy all the benefits with different people.

BUT here's what's IMPORTANT:

Almost EVERYONE wants freedom. But few are ready to give it to another person. This is the same pitfall of many "free relationships"

What is the bottom line?

If two are really comfortable in this format, this relationship can last a long time. Or, if in a sex couple someone expects, in fact, another - they will soon end in scandal and parting.

And now a question for YOU:

What kind of relationship format is acceptable for you and why?
