If anyone tells you that experiences teach you to hurt less, tell that person to fuck him/herself in the ass and jump from a 30-story-building. No, I'm not serious... about the 30-store-building, that is. You can choose your personal height.
Anyways, talking about getting hurt by another party, a.k.a (ex) boyfriend. Yes, my ducklings, the evil ex-boyfriends are there, ready to hurt you in every possible way that you cannot imagine. You thought you have learned enough in the past; you thought you have endured every horrid moment and heard all the nasty statements. Well, NOT.
I will not refuse to admit that, yes, past experiences do teach things, which kind of help me to move on. But these experiences, of course, DO NOT reduce the pain. Considering that I was facing a different person, thus encountering different ways of afflicting pain towards one another. Everyone that I talked to said the same thing. It's the gap; that huge deep bloody hole where your heart used to lay blissfully.
You are promised friendship afterwards, which is eventually adding insult to the injury. What's the point of being a friend if you are still oriented to the fact that you used to date your friend? Just give it a rest. Move on from the fact that there was used to be a relationship. We all want to forget it, because personally the relationship becomes meaningless when I know that the ending came easily and any efforts to fix anything was ignored.
Men are just... bunch of weird and nasty creatures that sometimes come to their senses, for a very brief moment. I still like them, but for God's sake, evolution should have not stopped.
So, if you're experiencing pain, make sure you: 1) have enough willing friends to just be there for you, 2) find a way to end your depression (if you're experiencing any), 3) pray that the universe will act fair and just, and that dickhead will get what he deserves sooner or later.
