Hello, M*A*S*H fandom! This is a longshot, but I'm hoping y'all might be able to help me find a fic I read on LJ ages ago.
It was a post-war fic with developing Hawkeye/BJ/Peg. Hawkeye and BJ were involved in Korea, and BJ hasn't told Peg yet. She's suspected based on how BJ talks about him and is understanding and encouraging about it.
Hawkeye hasn't been doing well with his mental health. I don't remember the context exactly, but it's possible his father may have passed recently or had serious health issues. He also hasn't been dealing well with the end of the war meaning the end of his relationship with BJ.
In the present, he's traveled to visit BJ. Unannounced, I'm pretty sure. BJ is freaking out a bit because he's worried Peg will figure everything out if she sees them together.
Some extra details I think were in this fic, though I'm less sure of:
-BJ takes Hawkeye away from the house to talk. I think they end up in the parking lot of an amusement park
-Hawkeye stays with the Hunnicutts, which makes BJ's anxiety about discovery worse
-Peg does become more certain about her suspicions after seeing them together
-Peg was pretty excited to meet the man from all of BJ's stories
-Peg approaches Hawkeye for a one-on-one conversation at some point
-Hawkeye attempts to initiate intimacy with BJ, who is conflicted. His feelings for Hawkeye haven't stopped. His feelings for Peg haven't changed either. He feels really guilty about cheating on Peg and isn't prepared to continue doing so in the States. He doesn't know how to reconcile all these things.
-Possibly, it's Peg who suggests polyamory as an option
-I don't remember if they're going for a full triad or a V
-Might have been part of a series?
