Textarea Line Breaks

Hey,

I'm trying to combine some array items to create a text area input with line breaks, but I can't get the line breaks to work. It works with wysisyg but I need the values to be read-only and dont want the large wysiwyg editor on my post edit screen.

Heres my code:

$address = 
      $this->form_obj['cust_address1'] . 
      '<br>' . 
      $this->form_obj['cust_address2'] . 
      '<br>' .
      $this->form_obj['cust_city'] . 
      '<br>' . 
      $this->form_obj['cust_country'];

Output in admin area:

https://www.dropbox.com/s/yjv4onkqn89qazn/metaboxtextarea.JPG?dl=0

Something similar happens with \n (the 'n' prints and there's no line break).

How do I get a line break in this situation?

Thanks
