That is what you need to do then. Sit back and wait for things to fall apart if that is what you think is going to happen. You don't want to be the cause of their break-up. Take the higher road.
Honestly, if my H were in a relationship with another women I would do nothing to be the cause of the break-up. (He was by email but it never turned into any physical.) I knew things would fall apart without my involvement. When I found out about her, I never called her or contacted her in any way whatsoever. H even warned her in emails that I may be calling. I refused to stoop so low. She was not worth my time. I wouldn't give her the satisfaction for a second. This way of thinking has always worked for me. I just let God handle things, and it always works out in my favor. Sorry if I am not much help, but that is how I see things.
