your day to day routine can easily distract you. weeks may go by where you forget about the thing you were trying to forget. and then somehow you are reminded...a smell, a car, a song. Incredible how your mind then brings back all the things it had been doing such a good job of repressing. 

then the awkward moment that deals with nothing of the emotional part of a breakup...the things you owe, the objects to give back, the custody of friends and sometimes even the resentment on the person because they're life may just be getting better...while yours may be staying the same. the selfish parts are the hardest to deal with because you know that in the end you'd only want the best for them. just waiting on the day that none of these things matter and they'll just be a distant, beautiful memory in the previous chapters of your life.
