I have had countless guy friends, and but on no occasion I had to tell them “I do not want to see you anymore!” Like a guy’s positronic mind all his relations are on a continuous radio-active decay path. Without any reinforcements/upgrades they deteriorate naturally. If I do not like someone, I will ignore him on a couple of occasions and the message gets across automatically. It’s a well defined spec, a protocol which prevents us to use of harsh words. Breaking up is like firing someone for the job of being a part of your life. And nobody wants to be a hatchet-man.
How wonderful it would be if someone could implement “Out of sight, Out of mind!” protocol in females.
Sometimes you end up in a relationship because “you are afraid of admitting the problem, and are too scared to walk away.”
