Summary:

A short conversation about soulmates and what it means. 

For The Seblaine Archive’s Seblaine Sundays - Prompt: Soulmates

Notes:

Work Text:

Sebastian doesn’t believe in soulmates, which, strangely enough, is the reason why Blaine believes they exist. 

There are a plethora of signs that all lead to the soulmate-ry of their relationship, and it’s not just chemistry, or compatibility, or even just love, that makes their partnership work. Those words feel too clinical, too temporary,  too broad— and what Blaine really believes they are, are none other than the old fashioned soulmates. 

“Why does Fate get all the credit?” Sebastian grumbles, putting his feet up on the coffee table before quickly sliding them off when he remembers how much Blaine hates when he does that. “I mean, I’m the one who did all the hard work to get you to go out with me. I’m the one who made you fall in love with me.”

“It’s because you’re my soulmate! It just came so naturally for us!” Blaine says, shoving Sebastian’s arm playfully. They’re sitting comfortably on the couch, some Netflix drama playing in the background, when Blaine wistfully looked over at Sebastian’s profile and said you’re my soulmate. To which, Sebastian replied, no, I’m your husband. Which then lead to Blaine saying yeah, but you’re also my soulmate— which, in turn, got Sebastian saying I don’t believe in soulmates. 

“Soulmates are for people who are single and are waiting for the one without putting in any effort to find the one. It’s a made up thing for losers and incels to cope with the fact that they’re lonely and no one wants them.”

“That’s mean…”

Sebastian scoffs. “I’m mean, and you still married me.”

“Because you’re my soulmate,” Blaine reiterates. “I wouldn’t put up with this if you weren’t.”

“You put up with it because I put up with you,” Sebastian corrects. “You think I give a shit about your Star Wars obsession? Or that you make me dress up as your favourite game characters for those game and anime conventions? Or that we have a million of your unfinished craft projects all over our dining table?”

“Hey! They’re still works in progress!” Blaine whines.

Sebastian points over at the mountain of crafts and canvases that have been collecting dust over the years. “We bought that dining table in the summer of ’22 and I haven’t eaten on it once since we built it. I’ve eaten dinner off your ass more times than I have on that dining table, which, mind you, costs twelve hundred and fifty dollars. A bit pricey for a craft station if you ask me.”

Blaine sighs, unable to refute that.

“I’m just saying,” Sebastian continues, a hand over Blaine’s thigh in comfort, “There’s no red string of fate, no name on my arm to tell me you’re my soulmate, no visions— no timer— none of that bullshit. It’s just you, and it’s just me— it’s just us. Nothing predetermined, nothing set in stone, no Gods in Heaven or Earth to tell me that you’re the one for me and I’m the one for you. Fate didn’t make me love you— you made me love you. And the word soulmate doesn’t get the credit for that.”

Blaine’s heart pounds hard in his chest, his cheeks burning bright red. How does he just come up with that thing off the fly? Blaine wonders. And it doesn’t help how Sebastian’s expression remains nonchalant, or that he lets out an unceremonious fart as if to reiterate his point. Blaine is still so irrevocably and dangerously in love with this man.

With hearts in his eyes, Blaine leans into Sebastian and melts against him. “But… isn’t that exactly the reason why we’re soulmates?”

It’s Sebastian’s turn to sigh. He twists his body to face Blaine, hooking his arm over the back of the couch in a stance that says he means business. “Okay, what’s gotten into you? We’ve been together for ten years, married for eight, why all this soulmates nonsense? You watching a new show or something?”

Blaine rolls his eyes, “No, no. Nothing like that…” He exhales deeply. “It’s just… Sam’s dating this new girl and they’re so compatible, it’s insane. She knows almost everything there is to know about him, and he knows almost everything there is to know about her, and it’s genuinely like they were made for each other, that they were destined to be together. And it just got me thinking how we used to be the same.”

Sebastian’s brows knit together. “Used to?”

“I mean, they’re in the honeymoon phase of their relationship. Things are full of light and whimsy and—“

“I’m gonna stop you right there,” Sebastian interrupts, a hand on Blaine’s chest. “Phase. They’re in a phase. Phases end. That’ll end. It’s only cute and exciting because they only know the good stuff about each other. And if she’s anything like Sam, it’s not too insane to know a lot of things about him. Hell, everything I know about Sam was against my will but even I know a lot of things about him and I’ve met him like, ten times in our whole ten years of our relationship.”

“Yeah, that’s true…”

“They have something fleeting. You and I built a foundation. You may think they’re soulmates for knowing everything, but even that takes work. You and I have a lot in common, but it’s not that that kept us together, and hell if it’s destiny or something lame like that that’s kept us together for all these years.” Sebastian brushes back Blaine’s curls that fall over his forehead and kisses his temple gingerly. “All I’m saying is, give us credit where credit is due. Soulmates are nothing more than a fantasy. We’re what’s real. Remember that.”

Blaine sits with that truth for a moment; he really takes the time to let those words sink in. He supposes he gets where Sebastian’s coming from; it does sound a little demeaning to chalk up all the pain and love and hardships they’ve gone through over the years to destiny and fate.

They’re meant to be because they’ve made it be. Not something predetermined, or set in stone, as Sebastian said. What are the chances of them meeting, getting to know each other and falling in love— going through the ups and downs of adulthood, careers, and family, and then getting to a point where they’re willing to bank on each other for the rest of their days? Was it really just fate? 

No. It can’t be. 

Fate didn’t do that for them. Fate didn’t secure their lives together.

It was just them and their love that made them what they are today.
