5 years is just long enough

Well, I've gone through almost 5 months without checking his FB. So why not set up a goal of 5 years? Not just FB, but on every single way of communication that may lead to a piece of information of him.
5 years is just long enough for a person to move from a period to another peiriod of a lifetime. Our mind will change. Our behaviour will change. Our look will change also. I'll be almost 34 at that time and will be at an important stage of my career. I believe that I'll have already forgotten about him before I reach to the end of this goal.
