In Deathly Hallows part 2Harry Potter and the Deathly Hallows: Part 2, we see themHarry and Ginny kissing, proving they were in love and later they married. But in Harry Potter and Half Blood PrinceHarry Potter and the Half Blood Prince, we see Harry trying to impress another girl in the hotel in the start of the movie. So were they not engaged in Half Blood Prince? There's also the whole angle of Ron getting jealous of Harry and Hermione during their trip in Deathly Hallows: Part 1 (even though he wasn't of a clear mind at that point). Was there any point in the movies where it was clarified that Harry and Ginny were an item before Deathly Hallows: Part 2 or was this just treated rather implicitly without even them realizing it themselves?
