what's up with you guys? never got the attention ov a girl?
syd, this is surely a very useful topic and i hope there isn't anymore bullshitting in here. forgetting someone is not easy particularly after half a decade. as it was once said, "Death is not the greatest loss in life. The greatest loss is when a relationship dies within us while we ourselves remain alive". But with the passage of time, one gets over it. leave him on his own. extreme thinking will eventually make him fed up and he will see other things in life. else, get him busy in new stuff without letting him feel you have sympathies for him. main thing we as Muslims can console ourselves with is that whatever Allah does is the best but we as humans do not know. message me for a few verses; don't want to be labeled a moulana here as well.
i really appreciate your concern. not many are lucky to have brothers like you.
