There is this 3 day rule given as a reasonable amount of time to reflect and weight things out,after an argument,pero it varies depending on both of you.Though we can just say it merely depends on what works best on both of you.For me mas better kasi after an argument occur ,give some time to calm down and try to reflect the scenario or situation.Madalas kasi kapag di ka calm down pareho it may lead to something worst,doing things you might regret later on dahil sa too much emotion that you've been dealing in a moment.There is a possibility that both feelings will be heightened which would usually lead to cloud judgement.Better give way for sometime and respect each others boundaries and feelings.Allow some time for both feelings to settle down first.Just don't let too much time before resolving it.
