Conclusion

Relationships are a part of most people’s lives, with most people beginning to have them around high school or college. As society evolves, more and more people are choosing to live together before marriage and explore their relationships with less initial commitment.

More and more people are finding love through digital sources and even using social media to better maintain long-distance relationships. While it’s true that many of them end (and about half of them involve cheating), that doesn’t mean they aren’t worth trying.

We have more ways to find love now than at any point in human history. And we are developing new types of communication and new relationship styles that fit our needs better than traditional marriage. So now, more than ever, it’s worth giving love a shot.
