I see three possible problems.
I could be wrong in my impressions.
PROBLEM 1
Who is this mentor? Have you asked them if they have different suggestions for full poly partners vs FWB?
Even though both use the same kind of board, how you play checkers is different than how you play chess, right? Expectations are different.
Even though wife is seeing you both?
- On this side you have a special needs son and a marriage.
- On that side it's basically a FWB/booty call relationship.
Explain to me why both sides would be treated the same at this juncture? Basic polite, sure. Could be polite to all people. But the SAME?
PROBLEM 2
You are using these interchangeably:
I think what you mean is "shared agreements" with your wife.
Your "personal boundaries" define what you will and will not put up with. What you will and will not do. Your wife doesn't have to like or obey them. YOU do.
"Rules" are restrictions you put on another person. I don't think that's what you are after here. I think you want "shared agreements" with your wife.
Super basic shared agreements?
- We both agree to use condoms and other safer sex practices with each other and other people. We both agree to get regular labs every X months. We both agree to ask/tell "Since the last time we shared sex, has there been anyone new or changes in risk profile? On my side there was..."
- We both agree we each get 2 days off a week from parenting. We can spent the time with dates, friends, family, on our own, etc. Even if at home? We are NOT the "parent on call." We check in every quarter/semester to mix the days up. This time period, my days are ___. Your days are _____.
- We agree we have our regular days as a family and as a couple. Family date is on ___ this semester. Couple dates are on ____ this semester.
- We agree we have our own personal banking apart from the joint acct that deal with kid/house bills. Our dates come out of personal. They do not come out of joint.
PROBLEM 3
I think you could go separate, parallel poly and expect wife to deal with her other relationships herself. If she makes a mess over there, it's her thing to clean up.
Right now? I could be wrong in my impression. But it's like you are bending over backwards to "include" Dude in your (you + wife) marriage agreements so WIFE will stop behaving all kid in a candy store wackadoo. Like "See how nice I am, including your FWB? So NOW will you stop behaving like a wackadoo and taking me for granted?"
Kitchen Table Poly (KTP) is not always wanted and it is NOT the place to start out at. And even then... KTP is made up of dyads. You still would have the (you + wife) dyad to deal with.
You + wife are responsible for that dyad. Not other people.
If she's behaving like a wackadoo at you, not respectful, standing you up, ditching the chores and childcare on you.... that is HER behavior SHE is doing, right? So deal with your wife and ask for changes in behavior.
You might be used to doing marriage "as a team" and that's fine. But Dude is not IN this marriage. You know that right?
There can be "working toward co-primary"
over time if everyone wants that. But she just started dating him! He doesn't get keys to the house or get access to your bank accounts or get to be in the wills or coparent the kid just like that, right?
It's ok for you to have some personal boundaries with your wife and with Dude.
And FWB can voice it to WIFE when they coordinate their calendar over THERE in the (Wife + FWB) side of the poly V.
You are not in relationship with FWB. You are not married to FWB. You don't have to deal with FWB at all.
Wife can deal with her own calendar coordinating with FWB. Just as wife can coordinate her calendar with you.
Why is that important to you?
If you make shared agreements with your wife, isn't it on wife to hold up her shared agreements with you? If FWB asks her to do something, isn't it on wife to say "No, thanks. I won't be doing that. I have shared agreements I want to keep with my other partner."
Aren't (you + wife shared agreements) created over HERE on this side of the V?
Can't FWB create (FWB + Wife shared agreements) on that side of the V over THERE?
If she's agreeing to everything under the sun with everyone she meets and she ends up spreading herself too thin... isn't that her lesson to learn? To NOT do that?
And who are you married to? Wife.
- So how is she respecting/not respecting this marriage?
- How is she respecting/not respecting you?
Why does FWB have to respect the marriage? Is he in it? Why does FWB have to respect you? Or you him? You are strangers to each other. Isn't "basic polite" good enough right now? Like if you happen to run into each other in town you nod and say "good morning" and that's it? Like you would do "basic polite" to the mailman?
I think (FWB + Wife) is their thing to deal with on their time. I don't know what shared agreements they have together apart from safer sex practices, but if you accidentally overstep on any, isn't it on wife or FWB to inform you? Then you apologize and don't do it again?
It is like you are worrying for EVERYONE here. How about you pull back some?
Wife and FWB could have that talk on their own time. It's not your thing to deal in.
If I was dating you, I would ask YOU. Not your wife, but YOU.
"Do you have any shared agreements with Wife or other partners that could affect me? In what way? On my side my spouse and I agree to use condoms and get regular labs."
If you wanted to share bare sex, I would tell you "No, thanks. I won't be doing that" because I have to hold up my shared agreements. *I* am responsible for that, not you.
You don't really know your wife as a hinge. So far she's getting carried away with NRE. So I could understand you feeling anxious about a lot of things. I understand wanting some shared agreements so SOME of the anxiety can be reduced. But you don't have to do your work AND her work AND FWB's work. Could let each adult deal with their own stuff.
