When his girlfriend randomly brought up a friend whose relationship blew up over Instagram messages—with her—he brushed it off.

But between the cryptic warnings, shady location sharing, and passive digs about his sister, he couldn’t shake the feeling something was off.

So he looked.

What he found didn’t scream “affair,” but it didn’t exactly feel innocent either…

Read on for the story.

AITA for feeling resentful and suspicious of my girlfriend, and for looking at her Instagram messages?

Recently there was a situation that’s been gnawing at me, and I’m not sure if I’m overreacting or crossing a line.

A while ago, out of nowhere, my girlfriend mentioned that a guy friend of hers got in trouble with his girlfriend over his Instagram messages with her.

She said the guy’s girlfriend “flipped out” on him, but didn’t really explain why.

It struck me as odd that she brought it up at all, since I hadn’t asked, and it felt like she was warning me—or planting a seed.

I’m not usually the jealous or suspicious type, so I just let it go.

Hm, all right…

But then I noticed some behavior that made me uncomfortable.

She’d leave her phone screen on and open to her location sharing screen and I noticed that they were sharing locations with each other—something she and I don’t even do.

It almost felt like she wanted me to see it and get jealous.

Eventually, I did something I’m ashamed of: I looked at the Instagram DMs between her and the guy.

Most of it was harmless—dog memes and whatnot—but there were also parts where she was talking negatively about me and my sister.

Uh oh.

She and my sister have had tension (mostly unspoken), but she’s never actually talked to her about it or tried to resolve it.

So seeing her vent to this guy about both of us stung. And then he sent her a meme that was pretty inappropriate.

She didn’t seem to push back at all.

Fast forward a few weeks.

She was trying to find out who in my family I confide in emotionally.

I mentioned my dad and stepmom, and she kept probing about my sister.

I was hesitant to say anything because she’s made it clear (in passive ways) that she doesn’t like my sister, and I didn’t feel like giving her more ammo.

Meanwhile, she’s continuing this oddly intimate (in tone) friendship with a guy whose own girlfriend was upset about his conversations with her in the first place.

Something is not adding up.

So, AITA for feeling resentful, suspicious, and ultimately looking through her messages?

I know snooping isn’t cool—but part of me feels like she was baiting me, and what I found made me feel even more off about the whole thing.

Reddit didn’t love the snooping—but they understood it.

While some called for better communication, others said his gut wasn’t wrong: something about this “friendship” felt disrespectful.

This person says he is NTA.

But this person says he kind of is…to himself.

And this person says everyone is in the wrong.

He broke a boundary—but she’s been crossing emotional lines for weeks.

It’s time for a come to Jesus, it sounds like.
