Cheating

lo

So my husband just told me that his co worker cheated on his wife maybe like two years ago but he just found out cause they were talking about it at work (they’re in the air force). I talk to his wife everyday cause our kids are the same age and we just talk casually I’ve only meet her in person twice. Anyways I feel like I should tell her. It ughh I don’t wanna be in the middle of it, plus I don’t want my husband to be mad at me or his coworker to be mad at him. I just hate it tho cause honestly I would want to know. I don’t even know what to do.
