Hey everyone, sorry this is my first post so I might write messy, gotta vent a bit. I'm 23, work as a homeroom teacher at a school in Hua Hin. We live together in a small house near the beach, just the two of us. When I'm at school I gotta keep up the teacher face and all that.

So last night around 10:45 I accidentally saw my girlfriend's phone sitting on the coffee table by the sofa (grey case with a little scratch) and a LINE notification popped up. It was a tilted selfie of her and some guy I don't recognize. They looked kind of close — heads tilted together a bit, a light arm around him... I can't say for sure it was anything, but it stuck in my head. The notification was on screen for maybe 5–10 seconds and I just saw the photo, didn't open the chat or anything.

I remember like two weeks ago she told me a guy friend from another province came to town and she wanted to take him for seafood. I said that's fine, no problem. But seeing a pic like that makes my chest feel weird, really uncomfortable. Like... super uneasy.

So I asked her straight up last night, "Who took this photo?" She said, "Just met up with a friend, don't read into it, he's just a friend." Her tone wasn't very enthusiastic but she wasn't angry either. I tried to believe her and said okay okay it's fine, but inside I'm overthinking like crazy, pissed off too. I kept listening to her answer to see if I could force myself to believe it, you know?

Another weird thing: she usually posts stories when she goes out, but when I checked her past stories I saw she had a bunch of stacked stories then deleted almost all of them. Only regular pics left. She deletes stuff super fast, like it's gone in less than a day, so that made me more confused.

Confused. So bothered.

I've been trying to control myself but tonight when we sat to watch a drama together I felt insanely possessive. Wanted to hold her hand but was scared it'd make her confused or make me look like I don't trust her. Scared the truth would break me, scared I'd be so jealous I'd ruin the relationship. Don't know what to do, super awkward ㅋㅋㅋ

Thinking whether to wait until morning and talk calmly but honestly, or ask her to open the chat and show me. But I'm worried about invading her privacy, and also scared of the answer. Maybe I'm overthinking, or maybe I should confront everything straight on and clear it up. Anyone been through this? Advice please.

P.S. Thanks for reading this far T_T I'll update later. I really want to hear real opinions.
