I've been fclosing a bit from Tinder lately and yesterday I matched with a pretty hot F25. Once the conversation starts going a bit, I usually tend to FB search them to get to know them a little bit before we meet, get the reconnaissance done etc.

Upon searching, I found out she's in a relationship currently. Most likely she's trying to branch swing at the minute and to be fair it pissed me off a bit. I've been cheated on before and I know exactly how that feels so I want to bush some buttons on that bitch.

TRP is amoral and I'm not looking for morality advice. I'd like to get to know what would be the best way to communicate the whole thing to her current boyfriend, without potentially getting any backlash from it? I know his FB details but I don't really want to expose myself. He seems like a decent bloke, but a typical beta, with photos of him and her all over his profile. Although it seems as if I shouldn't get involved, I feel like he should know. I used to be like him, in the blue pill bubble and I now know that she will cheat on him sooner or later.
