I used to think it is no point because you don't want to be reminded about the bitterness of the relationship. However, maintaining friendship in some way feels like you can still talk to this person who used to know you very well. Including starting arguments of the past. Or maybe just keep a distance and not chat (whatsapp) so much after the breakup? And what if both party still love each other but still have to breakup due to irreconcilable issues?
