While every relationship is unique, here are seven common characteristics that couples who have "made it" tend to display. Here are suggestions from a couple who have stayed together for 49 years
Have shared values and goals but give each other the space that you need.
Actively listen to each other and communicate openly.
Fight with each other. You are fighting means you are communicating about the tough things in life.
Partners who have made it provide unwavering support to each other during both good times and bad.
Treat each other with respect. In long run, respect becomes more important than love.
Never let a third person come in between your arguments, fights and your relationship. Not even your parents or children.
Find Peace. It may not necessarily be together. If you need take break from each other and spend some time to find your peace.
