Hailey Bieber seems to be emphasizing her husband Justin Bieber’s ability to protect his 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 related to the public or media pressure that Justin may be facing, and Hailey’s role as a wife who is there to support him, while also asking for respect for Justin’s privacy during this time.
She wanted to protect herself from the scrutiny of the process, as well as not have people pressure Justin to share or respond to any issues that arose when he felt ready.
