I disagree. First, we really don't know what kind of person she is. We don't know her personally, we know what she sees. And as a biracial woman myself, I can tell you that NOBODY willingly signs up to be mistreated. She may have been naive and blinded by love into beleving that race wouldn't be an issue, but seriously, noone would willingly enter into a situation where they're going to be treated the way she's been.
As for only her mum being at her wedding, again, we don't know her life. We know only what we're shown.
