I truly appreciate when people try to cheer you up after you broke up with your girlfriend/boyfriend, but there's one part i hate about it. The "plenty of fish in the sea" cliche. I mean, do people really think telling you that you were together with someone who wasn't good enough for you will make you feel better? No way. I find it very annoying. What is more, I don't understand why every time when you break up with someone all of your friends find so many bad parts of him/her. Can't we just get used to the idea that it didn't work? It doesn't mean that every person who you broke up with it's bad, stupid, ugly etc, it only means that it wasn't the right person for you, the person which suits your character, your heart. 

What happens when you feel that between you and your ex is something worth fixing and all the people around you tell you that you're way better than him/her and you just give up? You might lose someone who really cares about you and someone you could have been very happy with. 

So.. what I'm trying to say it's that every time when something like that happens you should only follow your heart and you shouldn't regret your choice whether it turns out for the best or for the worse because you did your best to make things work.
Indeed, there are some cases when you are totally blind and you are going to make a bad decision, but this is the moment when friends should really interfeer, because they shouldn't judge your ex, they are supposed to help you figure out what's best to do and to support you.
