Q. Have you ever invited another person into your marriage? If so, what was the outcome?
A. No, because it’s not possible.
People seem to think that they can build a house (a relationship) with someone, get it just the way they like it, then decide that they want it a little bit bigger, and merely add on a rumpus room to the back with no extra muss or fuss so that the house is mostly unchanged, just a little bit bigger and with little inconvenience to those who already lived there.
That’s not how this works. That’s not how any of this works.

Each relationship is its own thing, and requires nurturing in order to thrive. Even when 3 or more people are all romantically involved with each other, it’s not the same house just with more rooms. It’s more houses, perhaps all on the same property but sometimes not even that.
The more successful open relationships (and I define success by the happiness and satisfaction of the participants both during and after a relationship, not the longevity) operate on principles of individuality and respect for agency. Only when people who are partnered can see themselves as whole people, not halves of a whole, not partial people, not a relationship construct, are those people capable of having dynamic, vibrant, healthy, nuanced, 3-dimensional relationships with other people.
The people you get involved with deserve to be involved with a whole person, not a construct. They are not “joining your marriage”, they are relating to *you*, a human being, and anyone else they are getting involved with as well. That’s multiple relationships to maintain, not one giant relationship blob that just gets larger and subsumes everyone in its path.
I was polyamorous before I met my now-spouse. We got into a relationship as poly people and the relationship was polyamorous from the start. He and I have always had other partners and we had other partners when we started dating. Since we are both straight, the odds of us both dating the same person are almost nil.
However, one of his other girlfriends and I have a queerplatonic relationship that basically looks like a romantic relationship in all respects except for the sex. She was not “invited into our marriage”. He met her years ago at a kink convention that he and I and his other girlfriend attended. They hit it off. They began dating. She and I knew of each other through online poly communities, but after they started dating, we became very close and will remain “family” even if one or both of us ends our relationship with our mutual partner.
She is not a part of “our marriage”. She has her own relationship with him and her own relationship with me. Same as all of his other partners and he does the same with my other partners. Most of the metamours and metametamours (a metamour is one’s partner’s other partner) know each other and have friendships or other kinds of independent relationships with each other, so we have a large family dynamic together.
But each dyad, each partnership is its own relationship. And that’s the only way that each relationship can remain healthy.
