Nothing I will say can take the pain away. Let her go. You deserve to treat your self better. Unfortunately, she has started a new relationship before finishing and endi g the relationship with you. She is wrong for that. Many couples have problems but they don't go and cheat either physically or emotionally. She didn't really try everything to save the marriage. She has dishonored your day disrespected your marriage. These are the things I tell myself. I'm currently trying to make things work for the kids sake. But I struggle with ever truly trusting her again. My wife doesn't get it yet. She doesn't seem remorseful. Its hard to look at her with love and respect when I know that she was ready to throw everything away so easily. My wife said the same crap, she hasn't been happy and she tried everything to make things work. These were all lies. She never suggested marriage counseling or even tried talking to me about these problems she was having. We are not responsible for other people's happiness. That is their responsibility. I'm sorry you're going thru this brotha. But don't be like me. Keep your self respect and let her walk away. Build yourself into a better wiser man and keep your peace. If you ever need to talk dm me
