Relationships these days have become a routine in the sense of people are more in trouble than they spend in paradise. I think a lot of it has to do with people not dating but "talking" so they end up seeing a lot of flaws because they are rushing into relationships. Instead of taking that information and running with it they instead think they can change said flaws which in my opinion is the worst mistake. I feel there is a balance that is neccessary for a relationship in which you enjoy all the good traits you enjoy but you also accept the flaws and love said person for who they are completely. You have to learn to accept a person for who they are and not try to change them into who you want them to be and that is the first sign that there will be trouble in paradise. I also feel like the next problem is letting emotions get to the best of you that you make fights public weather it's legitment arguments or subliminal messages on social media it's like this generation feels they need to share all of their business which then allows outside sources to interfere with your relationship. An my last thing about the whole trouble in paradise concept is there will always be trouble if you choose to be stuck in a toxic relationship for the sake of "love" and "working things out" sadly some things don't work no matter how much time you put into it and you need to learn that it's okay to walk away from things for the sake of yourself, there isn't any rulebooks so your not forced to fall the social norms because even those norms aren't healthy sometimes you need to realize paradise starts within yourself. You must love yourself to understand what paradise is so when you go into a relationship you understand what you deserve and what type of shit you just won't tolerate. So just remember if you start seeing trouble in paradise analyze the situation before allowing yourself trapped into something unhealthy
