Well, she doesn't want to. When she made effort in her previous life to mold into his life style, he cheated in her, so she just doesn't want to make an effort. She think he is only worried about the last queen and her memories, and he never cared enough to resolve any issues between them before. Our girl is just tired of hoping (because she still does), and she doesn't trust him anymore to share all her plans with him.
And don't forget that she still thinks he was the one who sent assassins to kill her and (probably) her son too.
The misunderstanding is running deep and they are both in the right for not trusting each other
Lets not be hasty on making assumption and wait for more info, the enemy its someone that both of them knew, just like fl has her reasons for doing things in this timeline, ml had his reasons on his first timeline. (Both of them have the same plans but in a different way)
i think the commenter is just defending the fl. yes the fl and ml have the common enemy and ml's actions are reasonable, but that's because we have the grace to show empathy to the ml as a reader. they are both misunderstanding something, but the blame is heavier on the ml since he didn't try to communicate in their first life.
Well ladyship you're literally doing something shady rn behind herdin's back in this timeline where things starts from 0, you have memories, he doesn't so from his perspective you really are someone suspicious, understand your anger but when the person in front of you is clueless your actions will confuse just anyone. Spell it out loud, will you!!
