Will keep this brief.
Found out on Friday night that fiance (A) of a very good friend of mine is having an affair.
Group of girls out on Friday - I was the one not to know and was told about it coming home in the car. (A) wanted to stay out and begged me to stay with her - said no and came home in car with girl who was driving (B) and left (A) in town. Wasn't happy leaving her but she said she'd met an old friend and was perfectly safe. Was told that the entire evening, ie bumping into this guy had been planned all along - I thought she was texting her Fiance/DD but no apparently was texting this bloke.
Was told that 4 weeks ago at a night out (A) had bumped into this guy and brought him back to my friends house (B) (DH and I were away). Party went on quite late and when (B) was going to bed she heard someone in her spare room and went into check (A) was in bed with this bloke. (B) told me she was so shocked she just walked away. By the time (B) got up, (A) had gone but that resulted in frantic texting begging (B) not to say anything to (A) fiance who is one of our best friends. I've been told that (A) got home at 8.30 and her fiance came in off night shift at 8.50 am!
There was apparently lots of texting to (B) from (A) yesterday again begging her to say that we all came home together.
I hope all of that makes sense. I told DH yesterday and he is furious. I know we can't do anything other than if our friend specifically asks questions relating to Friday night that I will not lie for (A) and cover for her but I feel in such an awkward position because if our friend ever does find out and he knows that DH and I knew all along he'll be devastated.
