What Do I Say...?

A friend of mine messaged me a couple days ago saying she had white blisters on her lady parts. First thought in my head was herpes. 
She went to the doc today and the doc told her she was 98% sure it was herpes. 
Her husband was a man whore before they got married and they've been together almost three years. She said he had white blisters pop up on his junk from time to time and whenever he would get them they wouldn't do anything. 
She's really upset over it and has right to be because that's rediculous. What do I tell her to try to get her to feel better?
