Girls, Why more and more people are now unhappily married?

I started talking to a guy at the gym. He would always nod and say hi every-time he saw me for quite a while.

We got talking and it so how happened that he studied at the same university as me. He had saw me wearing the university jumper but he had studied 10 years ago before me. We talked about night clubs and how it had changed since he been there and what was still there etc.
He had completely transformed his body from the weights training also.

He mentioned he was married. That he met her back in university. how now has a kid with her and a mortgage. I said wow man , good you stick together. And he seems very negative. He didn’t have one good word to say about his wife. And he seemed generally unhappy. Also there is another women in the gym , who my friend told me he regularly talks to.
so it seemed common that people are unhappy with there marriage.
maybe now that he is muscular and bigger. He is more attractive and attracts more women more so than 10 years ago when he met his soon to be wife st university.
I have dated lots of women , and also had sexual relationships. But I am kinda scared to either marry one and be unhappy or have a child. So I am waiting for the right woman.
