She looks like this in public, wants to seem strong, because she doesn't trust anyone.
I agree with what you say in general, but I don't want her to SEEM strong, I want her to BE strong. Too many ''hard on the outside, soft on the inside'' female characters nowadays, I want someone who is tough on the inside too, but this is just my personal preference. That quote of hers ''I never NEEDED anyone, but I WANT you'' really got me, that is the kind of character I would love to romance.
