Bucky's presence breaks up Steve and Tony

[ladyhatshepsut.livejournal.com]

I'm looking for more of what Annehiggins calls "Tony falls apart because Budky is back" stories.  I have her "Never Gonna Happen," "Broken" by babygirl_me, and somanyfeels' twosome of "So Selfish" and "Only Fair."  I'd love to find more stories where Steve and Tony are a couple and happy together until Buck shows back up.  Whether it's Steve spending so much time trying to bring his best friend back to himself that he forgets about or just neglits Tony, or Bucky's jealouy coming between the couple, whatever you can recommend.  There's one story I recall where Steve kept trying to get a friendship goin between his best friend and his lover that he never noticed the hostility between the two, chiding Tony for his seeming dislike of Bucky, not realizing that it was only in response to Bucky's hateful attitude toward Tony.  Anybody know that one?
