Himari is turning out to be the "worst choice." If they did get together right now, she'd use him as an emotional crutch. Likely lead to substance abuse, and suicidal tendencies as she likely couldn't get what she needs from the relationship in the long term.
What she needs is to accept the love from those around her and learn to love herself. Leaving her "parents" would likely help in the short term. They need space to be bring themselves to the table to have some dialogue.
... This is turning into a therapy session for myself.
