Is there any fics where Tony’s love is unreciprocated? Then he gives up and suddenly Steve realizes his feelings but Tony’s done now. Or along those lines. THANK YOU! Have a nice life!

I don’t know if all of these recs fit exactly that request specifically, but you will find a lot of pining Tony and oblivious Steve goodness, so I think you will enjoy them!

WITHOUT COMMENTS AND KUDOS, AUTHORS ARE OBLIVIOUS TO YOUR LOVE!

But I Still Feel You by @pensversusswords: Tony knows a lot of things about Steve. He knows that
Steve is a stubborn pain in the ass, he knows that he’s got a heart of
gold, and he knows Steve would rather punch his way out of a tricky
situation than talk himself out of it. But the one thing Tony knows the most: he’s hopelessly, tragically in love with Steve. In which Tony is impulsive, Steve is confused, and they work it out in the end. Eventually.

Putting the Damage On by Innogenx: Steve Rogers is Captain America. Captain America is bigger than Steve Rogers. After
a break-up, Steve falls into bed with Tony. No big deal, right? It’s
just friends with benefits – no expectations, no strings attached.
Unfortunately no one told Tony.

We Accidentally a Relationship by @inukagome15:
In which Tony is pining and Steve is oblivious, and the Avengers and Pepper are not having this.

That Has Such People In It by lupinus:
Tony pines like a genius, and Steve is too busy being baffled by modern times to notice.

The Time the Avengers Try to Set Up Steve Rogers by Heartithateyou: So Steve is single, so the Avengers take it upon themselves to set him up.But its hard to say who’s more clueless about the whole situation.

Can’t See the Forest for the Pine by @musicalluna:
Tony is in love with Steve, only he had no idea.

Masked Man by @musicalluna:
Tony is in love with Steve, but Steve isn’t in love with him. It’s about
time Tony got over him. What better way than an anonymous hookup?

take my hand (take my whole life too) by superhusbands4ever:
Ok, so, Tony Stark might be a little in love with Steve
Rogers. But there’s no way Steve could possibly feel the same way. And
really, Tony had always been a bit of a self-sacrifical idiot. He’d do
whatever it takes to save the people he loves. Besides, whats love with
out a couple of near death experiences?

A Second of Totality by @stark-spangled-lovers: {TO•TAL•ITY | The moment when the light from the eclipsed sun is totally obscured}Tony
Stark is a lot of things: Sixteen. High school graduate. Child prodigy.
Obsessed with solar eclipses. And also hopelessly in love with his
ex-best friend Steve Rogers. At the end of high school, life sucks in a
not very sexy way, and there’s only one thing Tony’s looking forward to:
a road trip to witness the first solar eclipse on American mainland in
four decades. Over a week of world-stopping kisses and holes in the sky,
Tony finally gets a chance to tell Steve how he really feels. But can
the one short week end in anything but goodbye?

Of Course I’m Happy To See You by scribblywobblytimeylimey: Tony is always such a jerk to him – making fun of his
face, his body, and his personality, with a sarcastic “Prince Charming”
or “Goody two-shoes” or “GI Steve”. Or “sparkly-eyed bishounen”,  or
“innocent virgin”, or “Greek god”. Or “bedroom eyes”, or “first-time
stutter”, or “hung like a centaur”. Or “quit looking at me like you’re
sucking me off”, or “if you keep bending over like that, someone’s gonna
spank you”, or “you go ahead with the shield; I’ll take care of the gun
in your pocket”.In which oblivious Steve is oblivious. After all, he’s heard more legitimate insults in his time than horny come-ons.

Poster Child by sabrecmc:
Tony likes the new poster of Captain America.  A LOT.
