The heart does not learn. I thought that getting over someone gets easier with experience. It doesn't. There's no learning curve when it comes to the matter of the heart. I have realized that there's no correlation between how much your heart ached before and the intensity of a new heartache.
Like in anything else, I want to believe that experience plays a role in handling a relapse, it doesn't. As if the heart rejuvenates and wipes away all memories related. Therefore, relapse is easy. The heart detects that the feelings have been experienced before, however offers no defensive method.
