The question of a successful marriage remains open. What other options are there in love is met?

I look at our local newspaper. And there is an entire basement about one family couple who lived to a golden wedding. Our town is a big village, almost everyone knows each other. I ask my mom (m):
They say they have never quarreled in 50 years.
M: It is true. He has been passionate about tourism all his life, and she is a housekeeper. Like Friday, and I'm not talking about holidays, so he's on the trip, and she's home. I rarely see them fighting. Her husband, as she said, did not do homework. So they lived their whole life almost without crossing.

Well, we reached out in parallel courses even before the golden wedding.
An option that has the right to exist.
