Input: Kind of long story ahead

So, I’m not super close with this person (who we’re going to call S (20M)) but my super close best friend is and I used to be close with this person.

So S is not a actively bad person. He believes that cheating is bad. However, heres a little bit of background.

He was in a two year relationship with this girl and she was just the worst. They did not click physically/sexually and she basically belittled him and abused him emotionally. S wasnt used to attention though, so when they first started dating he got roped into the idea that she would be the only one that ever likes him. Really toxic stuff.

So S graduates and gets to college and meets this girl (we’ll call her M (19F)) and they hit it off really well. She openly says she has a boyfriend (one shes dated for like 3-4 years) but I guess M and S hit it off to well. They start a friends with benefits situation without M’s boyfriend knowing. 

At this point, my best friend and I obviously object but S has never felt this kind of “real love” before so he keeps going with her. However, hes starting to feel guilty, He keeps telling her its either me or him, we cant keep this going forever. M tells him some sob story every time though about how “her boyfriend is mean” and “she loves S” but she just cant leave her bf. S and our lil friend group are starting to see her sob stories for what they are and S comes to the conclusion that she probably wont leave because she just wanted something new and fun while keeping the comfortable aspect of having a really long relationship with said boyfriend.

S finally gives the ultimatum and she of course picks her boyfriend. Although S is heartbroken, he sticks to his word this time and cuts it off.

Heres the thing: Should someone in our group, maybe even S, tell her boyfriend he literally got cucked for half a year? I cant imagine thats safe for their sexual health if shes sleeping around with other dudes, plus theyve been together so long doesnt he have the right to know? A lot of people have said that my best friend and I shouldnt butt in, but I think our friend S would do it with some encouragement. And I would hate to know that the person Ive dated for so long literally cheated and no one told me cause “they didnt want to be in someone else business”. Cheaters should be shamed imo, and since S is willing to fess up then shouldnt M get exposed?
