That sucks, man.
I’ve been some stripe or other of non-monogamous for most of my adult life, and those types of relationships are often the ones that people experience first when they dip their toes in.
It’s honestly kind of maddening, because beyond making it seem like everyone who is poly/nm/whatever are all horny sociopaths (because almost everyone has something like that as a first story), it’s harmful. It’s physically and emotionally unsafe for the person who gets shafted. It treats people like they’re disposable and frankly, it’s selfish, insecure, and sometimes malevolent bullshit dressed up as a hippy-dippy love-fest.
It’s really fucking hard to be ethically nonmonogamous, and I wish people would stop pretending they knew what they were doing. No one knows, and it’s the faked confidence that gets so many people in trouble. People just trust someone to take care of them, and then the other person fails because they’re human, and humans fail. And yet… I can’t imagine not being this way, for some dumb fucking reason.
In retrospect I think my comment sounds like I’m just excusing being sort of crappy if you’re humble about it.
I wish I’d included the sentiment that we’re all trying the best we can — because being a good partner should be the goal for any relationship.
Even though I’m currently only with my wife, I’m right there with you. I don’t want to add anyone to the mix unless their addition is very carefully considered.
I speak better in metaphor sometimes: It’s kind of like physics, almost. Imagine that we’re touching everyone in our life. If we allow someone to connect to us, they are going to impart their own momentum and direction. That is going to ripple through every connection we have, even if we aren’t able to measure or observe it. So we better make sure they don’t hit us so hard that pieces break apart or get damaged in the process.
