Well, "need" and "want" sometimes break down into a semantic discussion. I think the point in this is that M realized that a poly life would be a good thing for her ... and by extension, for her and you, as well.
Quite frankly, that wasn't how it felt. I read in a different thread where the partner said something like, "I love you, I want to be with you, but if I have to choose between you and freedom, I will choose freedom." M said last night that's how she felt too. It's shocking how much she would give up for this. We have two kids, she isn't in a position to support herself, and few of her family and friends would understand.
This wasn't a well-reasoned choice, where all of us were taken into consideration. It was desperate, guilty, tearful and hard.
I have a passion, myself, for a business I've been trying to build for 15 years. It has been a source of conflict between us for a long time, and I've pursued it well beyond 'what makes sense.' But I can't give it up. There is something in me that needs to be expressed-- creativity, building something, a vision, a challenge... I'm complete when I have something like this in my life. It feels like a need, rather than a want.
To me, I need to have certain things in my life. Or perhaps, better said, I need to
express certain things in life to feel complete. I could be wrong, but that is how I see this with M. She doesn't need a specific other person, but she does need to express something that she can't express in a mono relationship.
Point being, when she figured out what she needed to express, it stopped being a choice. She is complete when she expresses it.
Here's the thing-- when I thought she could choose monogamy, I tried to show her just how much she had to lose, and I tried to boost myself up as an amazing person who deserves better. I wanted her to choose me and monogamy. It wasn't pretty.
But when I realized that this wasn't a choice for her, then I realized what
I had to lose, and was able to consider what
I was willing to do for us. If I hadn't made this switch, we'd probably be separated and miserable.
That is an amazing gift for a spouse to give, and I commend you for "leaping that chasm." It's not supported by society at large (yet), so it takes a great deal of introspection and inner strength to be okay with this whole "poly" thing.
Thanks, that means a lot.
