LF: Steve/Tony/Bucky Angsty Poly
So I am looking for a fic that was a Steve/Tony/Bucky pairing. What I remember most about it is that Steve & Bucky decide to get married to each other without talking to Tony. Tony gets heartbroken by the whole thing because they didn't even seem to notice he wasn't happy and after a fight Steve and Bucky say they'll get divorced to make Tony happy. Which of course it doesn't.
