Because they don’t really love their spouse? Or they have fallen out of love but instead of ending it, they keep the relationship for the security. I think most people don’t take marriage seriously which is why we have a 50% divorce rate. I was cheated on and decided never to re-marry because no one is committed anymore.
I really can not answer this question my friend. I do agree with you people do not value marriages anymore. Only God knows why.
You are welcome.

Thank you for your response. The question seems to be a tough one lol.
