Well, I think Capricorn should bear the brunt, because Capricorn is not very good at falling in love. Even if they are betrayed, they don't know how to deal with this situation, which is why I will put Capricorn first.
Next, I think this constellation should be Aquarius, because Aquarius has a blx. Even if I am betrayed by the other half, I still can't let go of my predecessor. So if I want Aquarius to do something for my other half, I think Aquarius is still timid. Aquarius will still choose to silently bear this betrayal and slowly get out of this dilemma, because there are many Aquarius around me, and they are all sincere.
Finally, this constellation, I think, should be Libra. Although Libra is the dominant constellation in the constellation, I think Libra can't measure love well, because his other half betrayed himself. How should he fill in this thing? I think Libra still chooses to minimize the damage, that is, silently bear the pain that cannot be expressed in words.
