AVClub: The inherent risk in any long-term relationship is that by opening yourself up to one person, you’re also opening yourself to be hurt more than anyone else can hurt you. You’re trusting them with a lot of yourself, trusting that they’re going to support you and look out for you. That can be a strength, but it’s also a threat where if things go south and a fight ensues it’s going to be ugly in a way that no other fight is. They know all of your weaknesses and know exactly what to say to hurt you, and more likely than not have a quiver stored up of things that they’ve thought better of saying in happier times. And even more dangerous, you have the exact same thing.
