<human>: So I'm not sure what to think. I'm very confused. These are my people, and we've been tight since we met almost 4 years ago. Two of them have been in a on/off relationship with each for 3 years, I was also briefly in a relationship with one of them,  and the other is married. Everything has been great, no tension, we were all happy. Things are more awkward now, with everyone pretending things are ok. They kept it a secret, and I feel betrayed. We had always had this party together before.

Am I right in how I feel for being left out? Most importantly, is this whole scenario messed up? Would you have the same reaction if it was you, and your friends?
Thanks to everyone who reads this - you guys rock
