I don't believe love is a battlefield. If you find yourself standing in that field, you probably need to get out of there ASAP. Not to break up necessarily, since a relationship can take time and effort, but you should reach an armistice pretty soon.
Love lifts you up, makes you strong and lets you face anything life throws at you. I don't mean it's easy or problemfree, but if the bad side starts to outweigh the good, it's time to reconsider the relationship.
As for WW, I think it's a truly sweet story of two people overcoming their own issues to be able to face each other as honest people. I think they both had a bit to go as the story ended, but who hasn't? We're all a work in progress.
