the star sanses and the bad sanses

Would they cheat/replace  you?

Dream:not in a million years, even when he ever turns to dust, he loves you dearly.

Ink:he would never, but he was always away protecting au's so you might be the one cheating on him

Blueberry:Blue is very dense and naive so there's a chance he might cheat but he doesn't mean it. The possible reasons of him cheating is he might've been drunk or was drugged.

_____
Nightmare (negative form) : of course he would cheat on you, but only because he was blinded by negativity seeing you as a toy to bear him his children.

Nightmare (pacified form) :he wouldn't. Your the only one that see through him despite the negative fruit the side of his tree bears...

Dust:before either of you could cheat on each other, he kills you for the sake of stopping frisk from resetting and resetting.

Horror:he doesn't find anyone in his universe interesting as you already are.

Cross:your dear to him, very dear to him.
