Moral Dilemma. what would you do?

i had a friend on EP named Oceandock. We went our separate ways when she became attached to a man. I attended a few parties where they were present, but it was obvious he was pushing me out of the picture.

I also observed that one of her friends was VERY interested in her BF at the time. Well on this trip i just came back from, she told me that Oceandock's now husband has been calling her and telling her that he loves her.

i told her she needed to tell Oceandock what is going on but she refuses. I just get the impression that she caused this to happen.

I don't speak to Oceandock anymore. She married this guy and moved away but it bothers me to know this info and sit on it.

What would you do? (hope this is not confusing)
