My best friend (F) of over 3 years is cheating on her husband with a random coworker of ours. I moved half way across the country with them too. Please help.

So I (25, M) moved with my best friend and her husband half way across the country so we all could get a new start. I don't live with them anymore but I do work with her and the guys she is banging. I'm decent friends with the husband also. They are my only good friends I have out here at the moment too. I just found out yesterday (she told me) that she has been going over to this guys house every day for the past week and having intercourse with this random coworker that she just started talking a week and half ago. I'm shocked and terrified on how fast this all of sudden happened. I told her she needs to tell the husband right away what's going on but she said she needs time to think about her options, which tells me she plans on continuing the affair if I had to guess. On top of all of this we have both told each other that we are attracted and have feelings for each other when we first moved here. We never acted on it of course. So now I'm seeing them at work and it's affecting my job and it's impossible to focus. The fact that I have feelings for this girl does not help at all. I can't stop playing the image of them being intimate over and over in my head. I haven't slept since I heard the news. Part of me wants to tell the husband but I know she would never forgive me. I don't know what to do and I'm so scared. I was wondering what my options are and what's the best way to get over her before I have a heart attack. Please any suggestions at all.... thank you.

TL;DR: My best friend (F) that I (25,M) have feelings for is cheating on her husband with someone that we both work with. It's affecting my work and driving me into a dark hole. I want to tell the husband because he is a decent friend of mine too but I know she well never forgive me. I need help and need options on how to get over her. Please any suggestions or anything.
