How to tell the fiancée of the man that I’m in love with that has and been cheating on her with me?Not yo be malicious but she needs to know

This is a tough situation, because no matter what you say, even if you feel like you're doing right by her, you're also still coming from a place of being in love with her fiancé and intending to end her relationship. You can't be objective in this situation, and she will probably be angry with you, which she has every right to be. If anything, I would recommend you tell the man in question to speak to his fiancée, as he is the one who has made commitments to her that he has now broken. He has an obligation to manage the situation himself. And furthermore, it will show that he is willing to take responsibility for his decisions. If he is willing to cheat and to let someone else clean up the resulting mess, that is not a good sign for any future with him. If he refuses to tell his fiancée, that is the time when I think you should tell her yourself.

There are a lot of things here. 1) You can ask someone to write a letter to his fiancee. Someone who is NOT known to any of these people. 2) You can tell this man directly, and ask him to be clear to his fiancee, 3) You can simply go away from all these people, find "TRUE LOVE" and not look back again. 4) Think from the perspective of the Fiancee, if your fiancee is cheating , what would you want to know and how would you react. In this situation, actions / decisions can be illlegal or immoral, like right now it's happening. Make your decision Wisely...
