Ok...Maybe i should say something related 2 topic... 
Sometimes, it's better not to know. For example, if you know u
can't be with the one u love, n u 2 can't be frens anmore, it's
better not to know how he/she is getting on in life...Yes of coz
sometimes u can't prevent urself from going to "click" on his/her
frenster profile, since updates are always shown on the home page
itself...
If u really want to forget him, what i suggest is maybe u can
delete him off ur frenster? It may hurt for a while but it's better
for you in the long run...unless u still have any hopes of u 2
being together or what...Just a suggestion...
