I think Flare's behavious does make sense, if you combine what she just said with what we saw in the GMG arc.

Ivan did beat her up if she didn't perform as he expected.

But being abused is something many people don't like to talk about, so Flare just glossed over this detail in the recent chapter. She's shaken up badly enough without recounting every little detail of her past torment.
