Should I tell my girlfriend's husband she's having an affair?

Anonymous
So my girlfriend is cheating on her husband. Things have been bad between them for a few years now and yes, I know both parties share some blame in affairs.

I know my girlfriend's husband hasn't been there for her emotionally or sexually for awhile. He pulls away from her and they have sex every few months and she says it's usually after begging and then it's really fast. She has tried to talk to him and get him to come with her to couples counseling for years. They've been married for 6 years this summer.

So she randomly started flirting with this random guy a few months ago and they fooled around and ended up having sex. She told me the minute she got home and saw her husband she knew she wanted to try to work things out with him. She says she loves her husband, believes they are soul mates, but just needed to have sex. So I thought, well ok then, I don't need to step in.

Now she tells me she has met this OTHER man who is married with kids who tells her he and his wife have an open relationship (ha, yeah RIGHT! Don't believe that for 1 sec. unless you talk to the wife 1st!) So the other day he was at HER HOUSE and they fooled around on her couch...then they met in a hotel room another night and had sex. Now her husband is out of town for the day and he's coming to THEIR HOUSE again to have sex!

It's eating me up inside because I also love her husband. He is a good friend of mine and my husband's too. I told my friend I wouldn't say anything NOT because I am protecting her, but because I believe it would be WAY worse for her husband to find out via me and puts me in a bad position too!

So guys, what do you think is the right thing to do here? I'm literally nauseous over it!
