Who is actually married for a long time and happy? Share your secrets with everyone else!!!?

My wife and I married just for what each of us are without any unreal expectation of the other. The first and absolutely the most important thing is when you marry someone , then marry someone who is a friend already and Keep being friends!Never think , "as soon as we are married,I,ll make these changes in him/her,it just doesn't work that way. We ,my wife and I operate on the same wave length you already posted in your question and for Twenty seven happy years!
