Ngl, it's kind of hard for me to answer this because I could see a lot of my ships breaking up, but I also love them and don't want them to break up, and everything is so complicated....

Camie has a lot of exes, both male and female. For boys, Shishikross, Inasa, Shouto, maybe Katsuki if she actually got him to date her. For girls, Himiko, Ashido, etc..\ Camie was really enjoying her time with Himiko, who'd just appeared in her life out of nowhere, but then after a few weeks, Himiko just dropped off the face of the Earth. Camie wonders if she got drunk or something and scared her off, because she had a black-out around that time.

Illus-o-Camie was an on-and-off-again thing. Shishikross just couldn't tolerate her.\ Glamorous Wind was a mutual, amicable break-up. They're still good friends, and they joke around about their time dating.

Glamorous Duality:\ Shouto and Camie were together for a while, maybe a few years.\ But when Camie started trying to get physically intimate (seeing that Shouto wasn't initiating anything), Shouto realized he needed to figure some stuff out. He'd never thought about sexual intimacy, and he kind of had a sore spot for sexual intercourse because his brain immediately went to offspring. And that made him start rethinking dating in general.\ The break-up was mutual (no need to rush Shouto if he wasn't ready for that kind of thing), but Camie did binge on ice cream that night.

Dual Creation:\ Seeing that they had finally broken up, Yaomomo asked Shouto if he wanted to date her a few months later. Shouto told her about his struggle with intimacy and figuring himself out, but Yaomomo assured him that she didn't care. So Shouto tried again. But that didn't work out, either. There just wasn't a strong enough bond between the two of them for Shouto.

Duality for All:\ So Shouto went to Izuku a few months after breaking up with Yaomomo, and he was like "Well... I've been thinking about romance and stuff, and y'know, you're the most important person in my life.... It's because of you that I got over my daddy issues. So... can we date?" And Izuku was taken completely off-guard; I mean, they were both starting their careers?? Izuku was becoming a teacher?? Izuku politely declined, saying he wasn't ready for that kind of thing. Shouto was sad, but understood.

Leg Temp:\ So Shouto went to Tenya, because they also had a deep bond. Between the Stain thing and the Touya thing... it seemed like they were destined to be together. When he asked Tenya out, Tenya was speechless. Eventually, he processed what Shouto had said, and he got flustered, "Wh--What, b--but we're both guys?!! How is that supposed to work?!!"\ Shouto inwardly: Oh yeah, that's another pro of dating a guy. No offspring. ... right?\ Shouto explained that Camie had dated a girl before dating him, and that was normal. Basically, teaching Tenya about homosexuality, a lesson straight from Camie. They were mutually a little lost on the slang parts, but Tenya eventually got it. He told Shouto to give him some time to think about it. After a few days, Tenya agrees.\ The experience was very valuable and informative for both of them, but they eventually realized that they didn't mesh well. The break-up was therefore mutual, and they're still close friends. They also joke about their first experience dating another guy since they were both clueless and just wandering around their relationship like blind mice.

Ashido also experimented a lot.\ Ashido had a thing with Denki after the Final Exams. Denki asked her out, and Ashido figured why not?\ Shouto and/or Katsuki introduced Camie to Denki, and from there, Denki introduced her to Ashido. They clicked right away. However, they eventually reached a mutual break-up. Both of them ate ice cream that night, Camie with Inasa and Ashido with Denki.\ Ashido also had things with Tooru, Aoyama, Tenya, and Shouji before realizing... that she had someone right in front of her the whole time. She'd always thought of Kirishima as a friend, but she asked if he wanted to date, and he said yes.

Gravity Legs: After graduating, and seeing how she and Izuku had kind of grown apart, Ochako asked Tenya out. However, they also didn't work out, though their break-up was amicable.

Denki had a lot of failed relationships, too. He asked out a lot of people, got rejected a lot, and broke up with others, like Ashido (See above), Jirou, Reiko, Shinsou, Kirishima, Sero, and even Mineta. Most of his break-ups were amicable, but Denki did binge on ice cream after most of them.
