In DH, the Dursley's have to evacuate their home because the magic that protects Harry lifts on his birth day and that exposes them as well.  Could it be that the reason Petunia took Harry in was to protect her family as well as him.  Perhaps DD explained to her in the letter he left with baby Harry, that if she didn't give Harry a home, her family was in danger from the death eaters.  So by giving Harry protection, she could protect her own family.  That would be a bitter place to be for her, her family is endangered because of Harry and he is their only protection.

So when Uncle Vernon was going to throw Harry out because of the dementor attack, DD reminded Petunia about his last letter.  So she knew that if Harry left, her family was in danger and she had to keep him.
