AITA for feeling jealous of my girlfriends new work friend?

A 28-year-old man is trying to act normal while his girlfriend’s new work buddy, John, basically takes up permanent residence in his head.

They’ve been together for two years, and sure, they work in the same office building, just different departments. But lately she’s been staying late, “finishing things up with John,” and even going out for drinks with him and other coworkers after long days. OP hasn’t even met John, yet the late nights and the post-work hangouts have him feeling weirdly left out, like he’s being replaced by a guy he never got to see in the first place.

Now he’s stuck between trusting her and wondering why the “just friends” story keeps showing up after hours.

Original Post

I (28M) have been with my girlfriend (25F) for about two years now. We both work in the same office building, but in different departments.

Lately, she's been talking a lot about this new coworker, John, who works in her team. She often stays late at work under the guise of 'having to finish things up with John.' For some reason, John really rubs me the wrong way.

I've never met him, but I can't shake this feeling of jealousy whenever she mentions him. I trust my girlfriend, but their frequent late nights at work together are making me uneasy.

Last week, she mentioned that they went out for drinks with some other coworkers after a particularly long day. They stayed out until late, and I couldn't help but feel left out and neglected.

I don't want to be the controlling boyfriend, but I also don't want my girlfriend to be spending so much time with this guy, especially outside of work hours. I've tried to bring up my concerns with her, but she dismisses them, saying that John is just a friend and that they have work to do.

Am I being unreasonable for feeling this jealousy towards John and wanting my girlfriend to cut back on her time with him? I feel torn and unsure how to approach this situation without seeming overly possessive.

The Real Issue Here

The OP's jealousy stems not just from his girlfriend's new friendship but from the late nights and after-hours outings with John. It raises the question of whether those late nights are purely work-related or whether they’re veering into personal territory. This is a classic recipe for insecurity, especially when the relationship is just two years in. Trust is vital, but it’s also fragile, and seeing a partner bond with someone new can easily trigger those fears of being replaced.

Readers can relate to this mix of emotions; jealousy isn’t a rational feeling. It’s deeply personal and often rooted in past experiences. The OP's struggle reflects a universal truth in relationships: how do you balance trust while grappling with your insecurities? That’s the heart of the debate here, making it resonate with so many.

OP hears “I have to wrap things up with John” one too many times, and that’s when his jealousy starts feeling louder than his trust.

NTA. It's completely normal to feel jealous in a situation like this, especially if your girlfriend is spending a lot of time with a new coworker. Communication is key, though. Try to express your feelings without accusing her of anything.

YTA. You need to trust your girlfriend and her judgment. It's important to have open communication about your feelings, but also respect her friendships and work relationships. Maybe try getting to know John before jumping to conclusions.

NTA. Your feelings are valid, but it's important to address them calmly and rationally. Express your concerns to your girlfriend without being accusatory and see if you both can find a compromise.

The real gut punch hits when she mentions drinks after work, and OP is stuck at home while she’s out late with John and the crew.

It’s similar to the AITA where someone felt overshadowed by a best friend’s new friendship.

NAH. Jealousy is a common emotion, but it's how you handle it that matters. Have an honest conversation with your girlfriend about your feelings and try to understand her perspective. Compromise is key.

It gets messier because OP hasn’t even met John, so all he has to go off is the pattern of late nights and the way she dismisses his concerns.

YTA. Trust is the foundation of any relationship. While feeling jealous is normal, constantly monitoring your girlfriend's interactions with coworkers can strain your relationship. Communication and trust are key.
