Knowing that you took the wrong road, hit the south wall, turned around and lived a good life, you should be lenient. Don't use this as an excuse to attack her personality. As a party (seriously suspecting that you are the man she cheated on), you can't attack others without humanity!
If we don't let them correct their mistakes and be aggressive, will we force others to die? It's inhuman of you to do so! It's immoral!
