The "dimensions of wellness" is a phrase you can Google and read more about. That one particular link if you click on the types, will give you some suggestions for how to address things in that "bucket."
As far as "IDing the things," then "brainstorming solutions" for the things, then sorting them into piles for, "How long does it take to execute the things?"-- that's just how I deal with some of my life problems. To me, it's part of
SMART goal setting. Getting it specific and getting it measurable are the first steps toward organizing a larger game plan.
Is that deceitful to her? Or is it just part of being in a polyamorous relationship-- that some things will be secret from the other? Is it ok not to tell her for the sake of peace?
That you even have to wonder, keeping info from her about the things that could concern her-- lies of omission are lies, hon.
If your partner is keeping his wife in the dark, you might wonder what he is telling
her that
you are in the dark about, maybe setting each of you up to "dislike" the other one, pitting you against each other so he gets all the cookies. From his POV, he has it made: a live-in GF tending to his needs, a wife dealing with the kids so he doesn't have to do a dang thing.
I'd be leery. Look at the huge stress ball you are under. What kind of dynamic do you
have over there?

Keep wondering. Take it all the way.
It is very easy to assign all your "ugh" feelings on her, but you could examine his behavior, not his talk. He may be one of those smoot-talkin' guys that just sliiiiiiide along in life. Examine his
behavior.
He SAYS he loves his children, but in his behavior he ignores them. This is loving how?
He SAYS he loves you and promises you whatever, but in his behavior he delivers
what? Or, does he only deliver partials? Just enough to get what he wants from you?
You guys seem to argue a lot because you are not getting what you need. Does he negotiate fairly and address the problem? Nope. You get this:
I am selfish. He has made sure to tell me that.
He does not attack the problem, but the person (you), which sends you into a brain cloud wondering if your really are being selfish. Result for him = you get off his back and do not hold him accountable for promises made. He's distracted you.
Marriage is something you value. You are starting to feel uncomfortable because that's another promise not yet delivered. It has been 3 years. The NRE has worn off. You are coming down to earth off the pink fluffy clouds, looking at your situation without the rose-colored glasses. And you don't like what you're seeing.
- You basically have to stay in a situation you do not like because negotiating for changes is getting you nothing. You don't like contemplating staying in UGH.
- Or you accept you got snowed for 3 years on fake promises-- and leave. I'm sure you do not like to consider that either, because you want to be able to keep loving him.
When life gives you stinky choices, chose the one that stinks the least. To me, that would be leave this situation. Your title says you don't want to play anymore. So get out.
Look:
I have no ring, nothing to indicate that I am "taken," and we have agreed that I am. We have agreed that my heart belongs to him alone, that it will never belong to another. He says that he will get me a ring when the time is right. And he is not one to lie. I want to believe him. But he never talks about it.. We never look at rings. NOTHING.
He wants to control how
you feel, that you will never love anyone but him? He dangles a ring like a carrot, but never talks about it? He's found your button to push to get what he wants. You want to believe him, but you can't. So you struggle to reconcile, because him stringing you along is less than loving behavior. His talk is all pretty, but his behavior is not.
He says he stays home to "side with you" when he avoids family things. But his behavior is what? Avoiding family things, now that they know you are the GF? Maybe he whitewashes it as "siding with you" to you, but really it is him avoiding listening to his parents tell him he's being unfair to himself.
Then it is really easy for the parents to continue to blame you first. Most people would rather blame the "outsider" than blood kin. Does he keep you away from the parents so they don't know you or your side of the story? Note how you don't get to share your side to anyone. You are isolated. Awfully handy for him. He can play, "I'm drunk with my affair. The mistress bewitched me," rather than, "I am pitting two women against each other so I get all the cookies."
I'm not saying that is what is happening. I'm only going by what you write, you, who knows what his side is.
But if what you write is the actuality and not your perceived reality, you could consider if that is happening.
Because it's sounding pretty weird there.
All things are negotiated, more or less, by him. If I have a problem I tell him and he talks to her about it...and thus far it has worked fairly well. But honestly, I have no idea what he told her in the beginning, or what she originally agreed to.
That's fishy. It sounds too much like "He makes all the rules." How do you avoid triangulation when all information goes through him?
I'm not saying you are being abused. But it's
weird sounding. Does anything else here ping for you?

Your last relationship was abusive. Have you healed enough and gained the relationship skills to stay out of more subtle abusive dynamics? Did you get out of the fire and into the frying pan? Not as bad as the ex-husband, but still not good for you?
You are pretty isolated socially. Are you isolated financially too? Do you have any money of your own? A job? Can you go home to the US and walk away from this? I'm not saying you'd want to right now, but are you even able to, if you chose it? Or are you screwed in Europe if this goes down badly? Left without the money to even get out?
I guess if I am to depend on myself for my own happiness, and to do what I need to do to make that happen, then I need to take any response from him out of the picture. Basically telling myself to accept it the way it is, find a way within myself to "like" it, or get out of it and start over. Am I understanding that correctly?
No. You do not have to "like it or lump it." Under normal conditions, you could always ask to renegotiate in for your needs. You can always ask. But what it seems like you are doing is blaming her for everything, or being
set up to blame her for everything so he sliiiiiides out of the spotlight for behavior done/not done. Blame shifting.
It doesn't sound like normal ethical polyshipping, if he controls all the information. There's a whiff of weirdness to it. It is very hard to tell from reading your story if you are a manipulative cowgirl, he's a manipulative weirdo, or what. I don't say that to upset you -- just telling you how it reads to a stranger. There's a whiff of manipulation in there somewhere, but who is doing it?
So my only advice is to work out listing all the things that bother you and try to group them together. Then maybe others can help you to see if you are too close to the trees to see the forest and you are not a cowgirl.
I assume positive intent on your part since you are the one posting for help. The more you write, the clearer it will become. So keep writing.
