If it is rationalization followed by REAL forgiveness-then I think it may okay if it is a one time thing, or some small slight that is unimportant.
If it isnt forgiveness, but actually just bottling it up-well that sounds not good. I dont think enfps are as good at being able to bottle up bad emo as maybe infps can. I think we emo-plode if we try and bottle up, so are kinda stuck either saying something or forgiving.
For myself rationalization works like a charm for anger-for hurt-oh, not such much. For growth, I need to understand how to better process emotional pain rather than just repress it. It is a lesson I am working through and I much enjoy listening to the INFPs here as they are very good understanding this.
How do your Fe users emo-vent? It isnt something I have seen but maybe I just dont have enough Fe types to watch?
