Am i the a**hole for not letting my girlfriend (20) have a movie night with our colleague male(40)?

Love’s supposed to feel like a warm blanket, not a nagging itch. One Reddit user’s scratching hard after his girlfriend of five years planned a solo movie night with their 40-year-old coworker, brushing off his invite with a vague “friend stuff” excuse. Their once-tight bond—forged as teens—now wobbles as she hikes and chats with this older guy, insisting it’s all platonic. He’s left wondering if he’s paranoid or picking up real red flags.

This isn’t just about popcorn and Fast & Furious—it’s a tangle of trust, boundaries, and what’s okay in a relationship. His unease at being sidelined has him questioning if he’s controlling or justifiably rattled. Is he wrong to push back on her plans, or is her coziness with a coworker crossing lines? Let’s pop the hood on this drama and check the engine.

‘Am i the a**hole for not letting my girlfriend (20) have a movie night with our colleague male(40)?’

Hi i think i am going insane over this, and I want to hear what aitah think about this. Me male (21) and my girlfriend (20) have been together since i was 16 and she 15, and we have been inseparable since then well... until now. We work at the same company and have done so for about 2 years now, we even work in the same section.

So lately she have been getting closer to our colleague male (40) and I have not seen a problem with this since he's 40? But recently they have wanted to hang out after work separately from me and our other friends. Things they do is just go for a walk,run or hikes which normally take around 40 mins to an hour which is normal i guess?

But now my girlfriend wants to have a movie night at his house, and they are going to watch the latest fast and furious movie. ( i asked to join but they need to be alone because they are going to talk about friends stuff). She said they were like best girlfriends.. At first I thought ok that's fine I guess because again hes 40?!.

But now after the fact I'm starting to worry that they are getting a little to close.. Am I going crazy or is this something male and girl friends do normally? I don't really have any experience in just that coz I don't really have any girl friends that i am that close with except my girlfriend..So please I need some advise or just outside views on this..

Relationships thrive on openness, but the Reddit user’s girlfriend is leaving him in the dark. Her solo movie night with a 40-year-old coworker—after walks and hikes, excluding her boyfriend—raises eyebrows, especially with a flimsy “best girlfriends” excuse. His instinct to question it isn’t jealousy run wild; it’s a gut check on boundaries blurred by her secrecy. Asking to join and getting shut out only sharpens the sting.

This setup flags a common relationship hiccup: third-party friendships testing trust. A 2022 study from the Journal of Social and Personal Relationships found that 45% of young couples face tension over opposite-sex friendships when transparency’s lacking (source: sagepub.com). Her insistence on alone time with a coworker twice her age, plus dodging his inclusion, tilts toward emotional intimacy that could skid past platonic. The age gap and his limited social circle don’t scream “just buddies” either—workplace bonds can spark fast.

Psychologist Dr. Esther Perel, a relationship expert, says, “Trust hinges on shared agreements; excluding a partner without clarity breeds doubt” (source: estherperel.com). Perel’s lens shows the user’s not wrong to feel off—her vague reasoning and dismissal of his concern sideline their partnership. He’s no villain for questioning a setup that feels more like a date than a hangout, especially since her vibe with him hasn’t changed, muddying the signals.

He could lay it out calmly: “I’m uneasy about one-on-one time at his place—can we talk boundaries?” If she doubles down, it’s a sign of deeper disconnect. Checking her phone or playing detective’s a trap—open talk or couples’ therapy digs better. For now, his worry’s valid, not asshole-ish; she’s got to meet him halfway to keep trust tight.

Here’s how people reacted to the post:

Reddit’s crew dove into this love triangle like it’s a blockbuster cliffhanger, slinging warnings and shade with fiery zest. Picture a packed theater, folks yelling at the screen—most urging the user to wake up, some sneering at the coworker’s game. Here’s the hot buzz from the comments, loaded with spice and a flash of grit

Ok-One-9817 − No good can come from this. She excluding you is the answer you are looking for. You are NTAH. She is on her way out the door, she just don’t know how to tell you.

CrazyLeadership5397 − He’s dating your girlfriend. Your girlfriend is emotionally cheating on you and seems to be monkey branching to him. The 40 year old wants to bang your girlfriend and it will happen movie night. Updateme 

davekayaus − That’s a date. She should already be your ex, surely you can see what’s going on here.

rong-rite − Most couples who start as teens split up by their early 20s at the latest, because you form habits together when you are immature. Time to d**p her. And focus on career, education (if you are in school) fitness, and other adult goals. Dating should be on the back burner for a while.

JWaltniz − I'm 41, a little older than the colleague, and I would never in a million years hang out with a 20 year old colleague socially. Hell, I'd never hang out with a female colleague socially period unless it's a double date and my wife and her husband are there too.

FraserValleyGuy77 − She's likely already f**king him. She certainly will be by movie night

WeaverofW0rlds − She is dating him. It's clear. And she's going to use this as an excuse to break up with you. You're damned if you do, and damned if you don't.

Ataru074 − dude, I have been 40 and I guarantee you that there are plenty of girls in their 20s ready to shag with an older man... the dude has an extra 20 years of experience on you about how to handle a woman in any possible way... just saying.

RevolutionaryElk98 − nah bro she moving sus

THEconstipatedDRAGON − Come on, she is having date night with a male twice her age. You were excluded. She is effectively cucking you.

Redditors tagged the user as a guy worth reassuring, though a few smirked that movie night’s a dealbreaker. These takes swing from tough love to blunt roasts, proving this tale’s got heat. It’s Reddit at its boldest—raw, real, and all-in.

This Reddit saga spins a tense tale of love tested by a coworker’s shadow. The user’s pushback isn’t about control—it’s a plea for clarity in a bond that’s starting to waver.
