Robert Pattinson as Edward Cullen in 'The Twilight Saga'
The most romantic men are always willing to make sacrifices for true love. And when sexy vampire Edward Cullen (Robert Pattinson) falls for human Bella Swan (Kristen Stewart), he fights his blood-sucking instincts to have her for lunch in order to have her as his girlfriend. When Edward tells Bella he wants to be with her forever, even proposing at the end of 2009's New Moon, he's not just talking about your average "'til death do us part" commitment. This immortal pledges his heart to his woman for all of eternity. Now that's loyalty! Thankfully, Twihards were finally able to see their favorite couple walk down the aisle in Breaking Dawn-Part 1 -- and it was everything they could have asked for!
