Over 50% of marriages fail in today's world. I believe the culture has changed drastically over the past 50 years along with technology and it has made relationships a lot harder. There is not a lot of privacy anymore in the world and that has a lot to do with it as well. People are just getting caught more now then they did before the internet and social media. Marriage is not supposed to be easy and if you don't work at it and society says its ok then people just give up on the relationship and get divorced.
