I just learned the BM's live-in boyfriend has cheated on her. (talk about karma). This is the man SHE cheated on BF with. I always thought I'd be gloating that she "got what she deserved" if I ever leaned of this information. I mean, BM had it made with a well-educated, well-paid man and she chose to leave him for a bartender/cook (not judging the profession at all) that hasn't been able to hold a steady job in the last 3 years. Instead, I am VERY VERY close to the person that was with BM's boyfriend. AND, she was extremely drunk the night it happened (yes, she has to take responsibility for that) and he took advantage of this fact. She had called me for a ride home and I unfortunately thought it was my alarm going off and I didn't answer the phone. She called a mutual friend of ours for a ride also and that individual didn't answer the phone. So, BM's boyfriend and his friend offered to take her home and another mutual friend told her she would be safe. Instead, they took her to a house that she wasn't familiar with and she ended up sleeping with BM's boyfriend. THEN, when he was done, he sent his FRIEND in to sleep with her. By this point, she began crying and the second guy had enough moral character to apologize and they took her home. Now, she thinks BM's boyfriend may have given her something. I was LIVID when I learned of all this. I knew he was pretty much a douche to begin with, but to offer to help someone in this condition then to take advantage of her is just about as low as you can go in my book. And, the night I learned of all this, he just happened to be in the same place I was and he was with BM! I caught him coming out of the bathroom and told him exactly what I thought of him for what he had done and told him he was lucky I wasn't at the other end of the bar telling BM what he had done, but IF he gave this person something, then she WOULD be telling BM. (Of course, knowing the things BM did while she was running around on my SO, it's highly possible that SHE was the one with something and gave it to him.) I really don't care whether BM knows he was cheating on her, because I feel like it's a case of what goes around comes around. BUT, where I am having some pangs of guilt are if this person finds out she was given an STD by BM's boyfriend, then I DO think this person should tell BM. I guess another alternative would be to tell BM's boyfriend that he has to tell BM he has an STD, but there is no guarantee he actually would. And the last alternative is to just let it go and whatever the two of them give/catch between one another is on them. Of course, the individual has not gone to the Dr yet to find out, but she's supposed to go this week. For her sake, I hope she didn't get anything, but if she did, I really do wonder if BM should be told?
