I just want to take a moment to acknowledge how hierarchy-centric this thread has been. Not to give anyone in particular a hard time, I just think it's interesting. Like, if we think that it's cheating to be intimate with someone else unless your spouse says it's ok, then is it cheating on the newer partner to be intimate with your spouse without the newer partner's agreement? Why or why not? For the record, I'm not taking a hard stance on this, I just think it's worth thinking through.
I also have to concur that this thread, while utterly fascinating, is indeed hierarchy-centric. This is not bad, as lots of people, including myself, have done or currently do hierarchy in poly relationships. I don't find hierarchy to be inherently unethical.
What is driving me a bit mad about the discussion is the untalked about, underlying assumption that
the point of being in relationship with someone else is to make them happy, or at minimum, not cause them pain or hurt them.
Lots of people have this assumption. It's wired into Western society, part of how we learn about love and being in relationships. On the face of it, it's certainly not unreasonable. I don't want to hurt my partner(s), I don't want to be hurt and I want to be happy - and I want them to be happy too.
That said, no one can make me happy, no matter how hard they work at it. It's not because I'm hard to please or always miserable. Neither of those are true. It's just that being happy, like being secure, is an an inside job and not something anyone can provide for us. It's not my partner's job to make me happy. (There is also the huge existential issue of if being happy is really a good goal to have in life but I'm gonna leave that one alone for now.) And no matter what I do, I cannot make someone else happy if they do not have it in them already to be happy. I always say insecurity can be a black hole for partners - you can pitch in all the reassurances, kind words and love all you want but if the insecure partner doesn't do the work to manage their insecurity and possibly reducing or ending it, that's just a black hole that sucks everything in, gives nothing back and ultimately it can kill a relationship. Trying to make a partner happy can be a similar black hole. I'm not saying don't try to please a partner, meet their needs and wants and so on. But making that the goal of being in a relationship sets that relationship up to fail at an impossible goal.
Also, it's not a good thing for a relationship where partners work to not hurt each other. Yes, it is terrible to deliberately hurt a partner, to be cruel, or to cause pain to hurt them so they hurt like you do. That is never acceptable in any relationship. Ever.
What is worse than not causing each other pain is to stop telling each other the hard truths about yourselves.
Being unwilling to cause a partner pain often leads to not telling that partner who you really are. The truth often hurts. It causes pain. It upsets relationships, causes chaos and turmoil. Our truths may not match up like they once did. Not telling a personal truth out of fear of hurting someone, especially someone we love deeply - while utterly understandable - leads us to hide from our loved ones.
I stopped telling Beaker my tough truths about our relationship because I did not want to hurt her. What I had to tell her would have deeply wounded her. That was incredibly arrogant of me. Beaker is one of the toughest, most resilient people I know. I stopped being authentic and honest with her and did not allow her the opportunity to be authentic and honest with me. This dynamic doomed our marriage. It wasn't our only problem but it certainly ensured that we did not work on resolving any of our issues because we could not even admit to each other that we had them. This is what I most regret in life. If I could go back in time, this is the one thing I would 'fix'.
For me, relationships are not about being happy, although that is a lovely benefit of being in them for me. My 'job' as a partner is not to avoid hurting my partner.
The reason to be in a relationship, what they are 'for', is to help us become who we most fully are, that allow, support and help us grow into being our most authentic, open, honest, loving self. If being authentic means I have to hurt my partner by telling them a hard truth about myself (or possibly them), then I am going to hurt my partner. I will hate it, I will not want to, I will regret their pain but I will do it. I've suffered through the high costs of doing otherwise.
If the point of relationships is to be happy and not hurt our partners, then yes, consent and permission are not so different. You each 'own' each other's' pain points and thus permissions allow each other to proceed (or not) without, theoretically, causing each other pain. (And they often don't work to prevent pain or ensure happiness.)
If relationships are meant to help us be who all we are, to become more fully ourselves, as I believe they are, consent is critical to being authentic. I have to have the ability to consent - AnnabelMore's point about needing the ability to retract agreement to have real consent is spot on - in order to be fully myself.
However, needing anyone's 'permission' to be fully myself just seems so ridiculous to me. I don't own anyone, much less those beloved people who have chosen to be in relationship with me. They don't need my permission to be themselves, to act in ways they find most authentic and honest and real. Sometimes those ways of being real are going to hurt me. Sometimes I am going to have to endure discomfort and pain in order so that someone else has the chance to be their best self. I will have to accept that paths cross, and then diverge as being ourselves take us away from each other. This is so incredibly hard. I get why we avoid it with all of our might and will. It hurts so much. But the alternative is so much worse for me. I will never give permission for someone to be themselves. I will never ask for permission to be the same. I will negotiate and talk about how to match our paths together, now to cope with discomfort, how to reduce pain, when possible, and when to take that pain as necessary. I will work very hard indeed at all those things and more. But I will never ask for or give permission.
