So it's revealed at the end at It: chapter two that Richie has romantic feelings for Eddie, but is unable to act upon these feelings as Eddie is, ya know, dead.
We learn that Richie Tozier, the fast-talking, foul-mouthed teenager (played by Finn Wolfhard) who grew up to be a popular stand-up comedian (Bill Hader) is gay and has been secretly in love with his friend and fellow club member Eddie Kaspbrak (played as an adult by James Ransone).
It Chapter Two made text what had only been subtext in Stephen King's original book: wise-cracking Losers' Club member Richie Tozier is a gay man, and has romantic feelings for his fellow Loser Eddie Kaspbrak.
In the adaptation of It Chapter Two, Richie is portrayed as being secretly in love with Eddie Kaspbrak until the latter's death, and Eddie remained unaware of these feelings.
Many headcanon that Eddie is present for the completion/addition of the 'E' after the defeat of Pennywise, for added closure and confirmation that Richie's romantic feelings were not only acknowledged, but reciprocated. To the lower left, it is also notable that there is an 'R' carved within a heart.

Did Eddie and Richie kiss?
As was demonstrated in IT Chapter One, the pair were close in the book — with Richie even going on to kiss Eddie on the cheek following his sacrifice. However, there was nothing to imply that their dynamic was anything but a deep friendship.
Throughout the series' run, Richie remained best friends with Fonzie, Ralph Malph, and Potsie Weber. He was always ready to help them out of trouble. He also looked after his younger sister Joanie as she grew up.
One of those attacks resulted in Losers Club member Eddie breaking his arm while trying to get away from It; he is left with a heavy-duty cast, which a bully defaces with a big old "loser." So Eddie attempted a little DIY redecoration, by turning the word into a makeshift "lover."
In IT, Richie (played by Finn Wolfhard) admits to his friends that he's terrified of clowns, which is coincidentally the default form that Pennywise takes on. However, in both the book and the 1990 miniseries, his greatest fear is a werewolf, and cutting this from his battle with Pennywise was a mistake.
“Beep beep, Richie,” Stan hissed, elbowing his friend sharply in the ribs and hoping none of the other losers had heard his comment. Richie had caught Stan eyeing Bill a few times now and, while Stan had still refused to admit it out loud, incessantly teased him about his crush.
Richie loved Eddie, and kept that with him his entire adult life, and now he's lost him. In hindsight, it makes sense, as Richie was always closest to Eddie, and it's possible his rampant sexual jokes about women as a kid were just an attempt to disguise his true feelings.
Richie always calls Eddie "Eds" or "Eddie Spaghetti" and has even called him "Eddie my love." He often calls Eddie cute as well, just to get a reaction from him, and Eddie is not always pleased about this.
Stephen King's IT introduced readers to a one-of-a-kind creature that can take any form, the most common one being Pennywise the Dancing Clown, and as menacing as it is, this creature has one big enemy it's truly scared of: Maturin, the turtle.
Richie was the most light-hearted member of the Losers' Club. The fear and terror didn't take control of him like it did the others. Richie had the nickname, "Trashmouth," for his constant use of foul language. That mouth frequently got him in troubles with adults and bullies in town, like Henry Bowers.
It turns out though that this was done to better reflect Stephen King's intent for the two characters. In the IT book, Eddie's wife is said to be a mirror image of his mother, who had passed away several years before Pennywise's battle with the adult losers.
Molly Atkinson reprises her role as Sonia, Eddie's Munchausen syndrome by proxy-stricken mother, and also plays Eddie's wife Myra, who is very similar to Sonia.
He was also nicknamed "Trashmouth", as he was foul-mouthed and loud, as he accidently insulted Henry Bowers and his gang. In the novel, it's assumed that he has ADHD, as it's stated that doesn't have much control of what he says or does.
He scares them and then kills them. This process seems to capture them in some fashion, presumably in his deadlights, which are closer to his true form. It seems like he doesn't enjoy killing those who aren't afraid of him, or perhaps he only has power over those who are afraid of him.
They reach the conclusion that Pennywise has all of the adults under some sort of spell that prohibits them from seeing him. The adults of Derry are shown to be villainous in their own right as well. The adults of Derry are shown to be true villains of the story in the same way as Pennywise.
It was said on page 1361 that the Spider being both female and pregnant was a symbolic interperetation. Its not literal, but a representation of whatever equivalent but inconceivable reproductive capability It actually has. Pennywise didn't become pregnant.
