It's hard and it can take a long time to get over a break-up. But, a good way to "move on" is finding productive and creative things to do to preoccupy your thoughts and fill your time.
Its very difficult to tell someone else how they should move on from something thats was special enough to have you even wondering how your gonna move on. My last relationship really took a lot out of me to where I thought I would never recover from it. Heres what I did; I tried my hardest not to sit around the house watching shows and movies that made me think of being in love or relationships. Not at least for the first month or so just enough time for me to start getting back out there and mingling not necessarily dating again just talking and flirting with the opposite or same sex if thats what you prefer. If there's anything your still holding onto for memories let it go!! It does you no good keeping things that's only gonna make you think of this person every time you look at it or pull it out of that draw you only kept those things. Tell your self daily when you wake up if you must that you'll be fine without them until you start to believe it. Eventually you'll be okay enough to where you won't have to even think about telling yourself that and this will all be a faded memory you can remember you overcame.
Hope that helps;))
