Hailey Bieber seems to be emphasizing her husband Justin Bieber’s ability to protect her personal space through this statement. She knows that Justin needs time and space to deal with personal issues, and when he’s ready, he’ll automatically speak up. This could be linked to the public or media pressure Justin may be facing, and Hailey’s role as a wife who is there to support him, while calling for respect Justin’s privacy during this time.
She was wanting to protect herself from scrutiny of the process, as well as wanting people to not pressure Justin into sharing or responding to any problems that came up when he felt ready.
