WordPress website integration

Hello. I want to integrate my WordPress into this website.
More specifically I want the the loop to go into the ‘news’ section, and i want a calender plugin to into the ‘calender’ function.

My wordpress website is installed here.

I think my problem is this line:
require(‘./wp-blog-header.php’);

I don’t know how to refer to it exactly.
My folders look like this at my server:
/www
—-
cupidcomebooking.com
blog.cupidcomebooking.com
—-
I’ve tried with this:
http://blog.cupidcomebooking.com/wp-content/themes/classic/header.php

still doesn’t work.
