Amber:
I went back and re read your OP.... I didn't see an actual threat. What do you feel Hol and Steve's ultimatum WOULD BE, if they made one? That they'd leave? Try to have you committed? M arrested? Go no contact with you until you cleared your head of this fantastical silliness, that is your life? My, God. What nerve, in any case, making threats of any sort.
I fall somewhere between Hops and CB's responses, btw.
I'd feel a burning necessity to calmly pee a definitive line around what's MINE to worry about, and what's Hol's to worry about. I'd ignore S's involvement, I think. This is between you and Hol, IMO.
Steve has as much say in your relationship with Hol as B does. B matters. He matters to you. S matters. He matters to Hol. You have boundaries around these relationships, as long as no one is getting injured, IME. It's hands off each other's relationships. Seems pretty obvious to me, but not to Hol. Not right now.
For what it's worth, it's looking like Hol and S about to overstep a very serious boundary, IME. I'd go so far as to use the term "interpersonal terrorism" IF they do make ultimatums. For me, that's very serious behavior. That's something requiring swift response, and very pointed sharing of information HOL and S need to make big boy and girl decisions going forward. They aren't children. They should know they can't tantrum their way into gaining your compliance, IME.
THis is what I don't get.....
Hol KNOWS you pretty well. What makes her believe this kind of ultimatum, if that's what it is, would gain your compliance?
What makes Hol believe she's the one with all YOUR answers, when she's got plenty to tend to on her own plate?
WHY does S believe he has any say in your relationship with B....
at ALL? Ever. In any way?
To me, that smacks of Hol and S sitting around, catastrophizing about WHAT IFs, and I get that. I've done it. I've lived in that head space FOR YEARS.
If S and Hol sit around, whipping each other into frenzies over your relationship with B and perhaps how scary B would be to deal with IF he were to become unstable..... controlling..... DANGEROUS..... violent in ways they absolutely wouldn't be able to handle..... that's honestly a pretty scary scenario to think about. I can imagine Hol and S are both living in their limbic systems a lot anyway, with COVID and Hol's loss of control in other areas of her life... work....the court.... her issues with fertility...... unhelpful coping strategies she'd do well to explore and tend to, herself.
Knowing you, Amber.....
in what world does Hol believe she has a right to leverage you into complying with her demands... and I'm not sure what exactly she's demanding, or what might happen if you fail to comply... again... you sense this is the direction they're taking. I wonder if that's true, or if they're just being what they feel is VERY FRANK about their feelings of what's true.
As you said, they're entitled to have their feelings.
You're entitled to have yours about Hol and S. Feelings aren't right or wrong, they just are.
There have to be boundaries, thought, for both you and Hol.
The men are partners, not mother and daughter. This is between you and Hol, IME. Hol needs and requires a very vivid picture of how things work, where she ends and you begin and what's hers to tend to and yours to tend to, IME. In some ways, I think she'll be calmed and reassured, like a child, when you set and hold healthy boundaries for yourself. You'll be modeling how to do it FOR HER, as well. It's ALL good. No need to freak out or get upset. Every need to be calm consistent mom, showing Hol how the world works.... helping her through it, but not enabling in any way or pussy footing around the information she needs to make sense of her world.
It's OK to speak up.
It's not OK to use interpersonal terrorism to force another adult to comply, or else.
Respectful behavior should go both ways. Anything else shouldn't be tolerated,
IME.
Nipping this kind of think IN THE BUD seems proactive and uber helpful, IME.
I know you're super capable of figuring out what boundaries you want in place, and what consequences would be appropriate, so I have no suggestions about that.
I know you'll handle this as well as it can be handled, Amber.
I think B will help you stay grounded, and able to be responsive, which is what Hol needs right now, IME.
