Just remembered a few things that were flooding my mind for quite some time.
I never actually understood of why people were so surprised and taken aback of Ascended Astarion not accepting his partner fully transformed into illithid. Like... were everybody really expecting him, now being free from fearing opinions of other surrounding him and their judgement, to accept the very thing he despised from the very beginning, even before Ascending? There were so many times said personally by himself throughout the game that he hates mind flayers, he *isn't* a fan of tendrils, he sees them as monsters and has no desire to become one himself (of course, only Minthara out of all group eagerly accepts the astral tadpoles and dgaf, but the way Astarion tried to defend himself that he doesn't want to do something against his own will once more... I will never even look at that persuasion option in answer to make him change his mind).
Consider it more of my personal opinion, as always, or even my projection, but when I see spawn Astarion behaving right the opposite way, accepting illithid MC... I had been in toxic relationship where I had to accept the person's look just to stay together with them, fearing I will be left alone if I wouldn't. I can't view this as anything happy or even healthy. Of course, if I had therapy I could maybe have seen a different angle to it... But not now, obviously. (upd: my memory has twisted things a bit and it's better in game, skipping that part of my text wall.)
I don't think that this, however, has any real life associations, because it's not about something like losing your limb, your face, your mind etc, it's about turning into entirely different kind of creature, which is fantasy-only case. And seeing AA getting blamed as abuser for all of that is wild, as always.
Perhaps people stick to that "will you still love me if I was a worm (in this case, a squid)" too much, I don't know. AA definitely won't, not in the same way as before; nevertheless he still saves the connection between himself and MC. And I don't see a problem here. He doesn't have to pretend and he has all the freedom to say "no".
