I agree with the people saying that time will heal the wound. But in my opinion it is also up to the person. In german langauge "Die Dinge haben nur den Wert, den man ihnen gibt. (Molière)" that means, "Things only have the value that we give them (Moliere)". So it is "also" up to the broken hearted person to heal himself/herself, because maybe the person gave the realtionship or the fact that broke his heart a too big value. Of course friends can always help. Not with talking about the problem but with beeing nice, and doing stuff like going out etc.
