Let's face it a few things have changed over the past few years.
1) People's view on religion has changed over the years, more people are becoming either atheist, agnostic and/or spiritual, but spirituality is the bigger one of the three. Tthe "traditional" belief in marriage has weakened in a lot of people's own eyes, except of course for the crazy extremists who kill their families and themselves if things go awry.
2) The internet. The ease of meeting people, takes seconds and that's it, done. Meeting and talking to people face to face on the street, in a store, work, wherever isn't as prevalent. ie - dating sites/apps and forums.
3) The internet (again). The influence of media through the internet, videos, etc, people have some become so insanely materialistic, self-absorbed (selfies, who has more friends, people looking for adulation, etc).
Society as a whole has changed immensely and I don't think it's going to get any better either.
TheSe are my opinions, they're not right or wrong, but I think I'm kinda/sorta right to a degree. lol
