Broken,
u're sooooo not alone....i was EXACTLY in the same situation as u. i actually went into this forum a while ago, and made a post under heading "how to forget"...u might wanna have a look at it...i got lots of good response from people here (thanks guys)...
i really understand how u feel, and all i can tell u is that mine is alot worst situation (mine is 10 yrs of not being able to forget!!!) but then...one day i came to realise that i was destroying myself. i was extremely exhausted, because i cried every night, and felt so miserable. (just like ur case, he told me that i was still his best friend, yet he never actually talk to me as much, when he found out what i really feel abt him). anyway....
so here's my suggestion for u (proven to work in my case):
1) pray. (really..it does help)
2) surround urself with lots of good, and POSITIVE friends
3) keep urself really busy with things that u like
4) look after urself well by watching what u eat, exercise, and glam up! make urself feel (and look) better.
5) cut out any contact with him, until u r trully over him. even if it takes months, so be it! dont chat, talk or meet him.
finally:
6) learn to accept the fact that he's gone. don't hold hopes, and keep positive thoughts. dont look back, and asking "what if".
good luck....
when there is no more words left to say. when tears have no more meaning, what would u do?
