In my opinion you have already found the meaning to love free and you have already broken out of societal expectations of mono relationships (but even that differs per individual mono relationships). Just think of it this way: every person is unique and whoever loves you should love you for who you are and the other way around.
Do not let the term polyamory distract you into believing this is a set lifestyle with pros and cons and do's and donts. Maybe the difference is that there aren't any. It is open and with being open you will never be unfaithful to anyone.
I am from holland myself. Don't say dutch people have it the easy way as we are such open minded people as that is how people here just ACT conforming societal expectations.
