2. You Live For Each Other
You can no longer imagine how your life must have been before you met her, and it must have been so boring and incomplete that you don't want to. You are each other's lives now and you will be able to conquer anything as long as you have her shovelling food into your mouth by your side. She is the best thing that ever happened to you and she makes you a better person. There are times when you want to kill her but those moments are extremely rare, and when they do happen, you both bring up each other's mistakes since you first met and then get over the whole thing ten minutes later.
