To 'allow' your heart to stop loving your ex is hard - it means admitting to ourselves that the relationship is over, and that we will be okay - no matter what. To allow your heart to fall out of love means to open it back up and 'allow' others in. You can speed up this process by either getting rid of anything that reminds you of your ex, or by packing it away - out of sight. By clinging to the love you are not keeping the relationship alive - like your mind has convincingly deceived you into believing - all you are doing is keeping the grief alive. So here's some suggestion aight.. Get new interests, change something about yourself or your life that you were dissatisfied with, find new hobbies, join clubs or groups and make new friends. This is a time of rebirth for you - a second chance at life - so go for it with all the gusto that you possibly can!
