:: No matter how many google hits is has, or how much the term applies to fiction, this article is still an unsourced, POV pile of crap. I think we should delete this entry. Or how about this: Create a wiktionary article for it, and in a few sentances, define "love-hate relationship". 
In my opinion, nobody is going to be able to write more than a paragraph of a encyclopedic quality description of "love hate relationships" because the term is so straight forward. Thus, much of the article is either going to be trivia (examples of Love Hate Relationships in books and movies), which wikipedia discourages, or made up explanations of love hate relationships (what the article is now). An exception would be if somebody found some academic research that explores the properties of love hate relationships. Then we might have something to base an article upon. 
In the mean time, Im removing some large areas of unsourced statements from the article.
