"They ate every day at the same table and from the same dish, and at night their beds did not separate them. And the king of France loved him as his own soul; and they loved each other so much that the king of England [Richard's father] was absolutely astonished at the passionate love between them and marveled at it."

Probably so. That kind of language is suspect today, but common back then for friends.
The same trick is used of David and Jonathan in the Bible.
Sick tricks.
