sometimes, when it's over, you would still cling on to that little hope. i think its alright but you must have the courage to move on and condition yourself that your situation is different now. and its better that you look at the reality rather than fantasize on what could be if you got back together. i got this advice from a friend, and i believe it makes sense... its better to be empty rather than be in pain.
you may have a different view, you might rather choose to be in pain because it gives you the ability to feel and that its more human. but i guess in my case, i had enough of too much feeling and emotions and the best way to go right now is to rest. it doesn't mean i'm giving up with happiness, its just a phase one has to go through to reflect on things and realize your achievements, strengths and weaknesses. i suggest you let it happen in your life, to have a moment of silence and contemplate what has transpired. this way you don't focus on the negatives, but on the happy memories and the lessons you obtained.
i'm now counting the days to my big 3-0 and much has happened, good and bad. i'm now halfway of my entire life, and wasting it on bad memories and sulking is not a good idea. i choose to be strong and happy... i'm gonna move on with my head up high because i know i did my best for the past 30years.
