idk if i'm ever going to fully articulate the kind of narrative tension the obikin-obidala-aniobidala dynamic can have in terms of…"unstoppable force meets immovable object." the parallel their conflict can have to canon laying the different paths they could've taken as: Necessary Growth, or Ruthless Dominance, or Mutual Destruction.
obi-wan's character has this motif that's foiled with anakin in canon, but that can be extended to padmé as well, where obi-wan is this consistent pillar of set principles, that he holds anakin and the jedi to those standards as well, and how strongly it contrasts with anakin's loyalty to self-interest at worst and individuals he's close to at best. he and padmé can be impulsive, are shown to stick to morally gray decisions after years' worth of outs that would've been bloodless, and in the end the instability they have individually and enable in one another is part of what leads to their downfall.
and there's something to be said about why they choose unto the very end not to go to obi-wan, why anakin prefers to confide his darker inclinations and acts to only her and palpatine. because obi-wan is someone who allows and even encourages consequence. if he knew about the massacre, he would have anakin face it. if he knew about the marriage, he would have anakin choose that or the order. he already doesn't hide his wariness towards their romance in its earlier days, irate with anakin and padmé both in the novels; he wouldn't bother to hide how upset he'd be at discovering their marriage. part of anakin's resentment towards him in aotc is that obi-wan is not "easy"; he doesn't punish anakin outright, but he rarely softens the blow of shortcomings or failure, believing that's a part of learning to be better, to grow.
it can be easily perceived as rigidness just as anidala's conviction to attachment can be seen as reckless, and in a context of all three of them wanting each other, there's this facet to obi-wan being a central part of this dynamic that's genuinely attractive in that…he can come across as someone, in that steadfastness and in those set of standards, who demands growth from these characters in particular, who in-turn may stronghold him into bending to them or try to overpower his convictions outright. it's that condition that obi-wan brings to the table where the consequence to padmé and anakin unwilling to meet near his level is him just leaving, severing ties. for two characters whose main conflict and motivator for both their narratives is attachment (or what they perceive is love), that could feel like abandonment, or a threat, especially because obi-wan is capable and, since it's a consequence, he won't make any effort to hide why he might cut them off in some fallout.
and so it leads to this road and these questions of: who bends, how much can be given, and how far? how much truth is revealed at first, and what does the resolution to this dynamic of all-for-one, two-versus-one, look like: Necessary Growth, Ruthless Dominance, or Mutual Destruction? anidala as a force fueled by adoration, with-and-versus obi-wan, whose expectations for loved ones can be just as ruthlessly exact, and who'd bring both needed stability and novel tension. that's a dynamic that, if executed well, would be really fun to see.
