I was in a 'relationship' for a year and a half. Technically, you could say around three years, considering myself and her were practically the "bestest best best friends ever," and all that jargon. All the stuffed animals, candy, and plush puppets couldn't make up for the times I wasn't able to be there for her, which was something I failed at being there, and she failed in learning how to cope with her own problems alone, in my opinion at least.
So, after she puffed up and left in a huff after my being the worst asshole towards her, due to her constantly giving me nothing but negative feedback, I spent about two weeks in a state of deep depression-ish. Cried at home, cried at work, and I didn't really have anyone to talk to about it, per se, and eventually just got over it by the cold fact that I'd have to learn from those mistakes, and that they weren't evil - merely stepping stones to learn from.
Did I learn how to better manipulate the average girl into a near-perfect blissful happiness? Yes. I learned how to better recognize problems, and verbalize my opinions and such in forceful, intentionally non-offensive ways. It could be called 'suffering,' but at the same time, I don't bother seeing it as such. Just a learning experience, nothing more.
Thanks to everyone in #junes for giving me fits of laughter during those two weeks of cow manure.
