Always , always communicate . Remember to always be their best friend and confidant , make sure they know they can always talk to you about their troubles . When they talk , listen . Listen hard even to the most mundane conversations because you ' re supposed to be the one person they can always count on who will never let them down , and that starts by being the best listener you can be . Do everything you can to never let them down . If you let them down , make it up to them . Never say things when you ' re mad , you never know what will haunt you or worse change your relationship . Above all else , remember that being in a relationship means you stand by them , love them and do right by that person no matter what happens .
