I’d never come across the word Metamour until I started reading about polyamory.
The literally meaning of this interesting word has two simple parts, meta = with; about & amor = love. So basically the partner of one’s poly partner, with whom one does not share a direct sexual or loving relationship.
e.g. My husband’s girlfriend is my metamour
Life as the pivot between two people you care about can be complicated and a bit of a balancing act but we’ll worth the effort.
Being a Metamour may have certain connotation related to it depending upon the shape or structure of your relationships. Inversely if your on the other side, just because a metamour is somebody with whom you don’t share a direct loving relationship it is still important to understand that you still sharing a relationship with them of a completely different nature. You’re sharing time, energy, and commitment. You’re sharing another person.
So be prepared, this is another relationship that requires time, energy and understanding. I can’t stress how important getting this dynamic right can be, it is laying the foundations for the future.
