wow six years is a long time to be yearning for someone who is not interested in returning your affections....might be time to look for another job or transfer to a different department....will give you a fresh outlook....write a letter and tell this person you had a wonderful six years longing for something more but it is now time for you to move on.....of course you can send the letter or just file it away ....it is a symbolic step of ending this relationship and freeing yourself to be open to new possibilities....i wish you all the best....beechwood
