My gf is on a 2 day goa trip with her male bestie and is dressing very slutty should I be worried

My gf is on a 2 day Goa trip with her male bestie and is dressing very slutty should I be worried?

Idk if I'm overthinking like crazy or if anyone else would also be suspicious here.

My gf is in Goa for 2 days and she went with friends including her male best friend. She always told me nothing has ever happened with him and he's "like a brother" etc so I never wanted to be that controlling bf.

But yesterday was weird af.

She video called me before going out and honestly her dress was insanely short. Like when she turned around the bottom lining of her bum was almost visible and from front the cleavage was VERY deep.

I even said wtf you're actually going like this 😂

She just laughed and said "baby its Goa chill"

Around 8 she sent me a pic from the party and she was standing super close with this guy and his hand looked around her waist.

Then after 8 she literally DISAPPEARED.

No reply nothing.

I texted 10ish. Then again later. Called around midnight. Nothing.

And apparently the others didn't even end up going properly so it was basically HER AND THIS GUY partying together.

Then fucking 4 AM she suddenly texts

"sorry baby was asleep"

Like what???

I called immediately.

Declined.

Called again.

Declined.

Third time she finally picks video and this call is literally stuck in my head now.

Her hair was completely fucked up messy. Makeup smudged. Lipstick basically gone. She looked flushed and sleepy and she was very obviously not wearing that dress anymore.

She had something pulled around herself and kept the camera from shoulders upwards.

I asked where are you.

"My room baby I was sleeping."

Except I had literally seen her room earlier.

THIS WAS NOT HER ROOM.

Different bed. Different headboard. Different lamp.

And the fucked up part is I'm almost 100% sure it was HIS ROOM because earlier he had put a story and I remember the same headboard behind him.

I asked "is he there?"

Immediately she gets irritated.

"No??? Stop being weird."

Then for like one second she moved the phone and I saw the bed behind her.

Bedsheets completely messed up. Clothes or something on floor. Then she instantly moved camera back.

I swear I also heard something behind her like someone moving or a guy saying something quietly.

I said show me the room then.

She goes "wtf no I'm sleeping goodnight"

AND CUTS THE CALL.

Next morning she's acting totally normal and still saying she slept in her own room.

This is where my brain is fucking me because now I keep imagining what actually happened between 8pm and 4am.

Like they were alone drinking for hours, she was already being really flirty and dressed like that, maybe they came back to his room still drunk and sat on his bed talking.

Maybe they got too close.

Maybe he kissed her and instead of stopping she kissed him back.

Maybe all that "he's just my best friend" shit disappeared once they were drunk and alone.

In my head I'm imagining him pulling her closer by the waist, them making out on his bed, her dress coming off and them ending up sleeping together.

And that's why when I called at 4 she panicked.

That's why she wasn't wearing her dress anymore.

That's why her lipstick was gone.

That's why her hair looked like that.

That's why the bed was destroyed.

That's why she wouldn't move the camera.

My brain even keeps imagining that maybe they had literally just finished hooking up when my name suddenly came up on her phone and she had to scramble to cover herself and answer me while he was still there.

Like imagine your gf has just slept with the guy she tells you not to worry about and then 2 mins later she's video calling you saying "baby I was asleep."

That thought is honestly fucking destroying me.

And yes I KNOW none of this proves that's what happened. That's literally my imagination filling in the missing hours.

But then why lie???

If nothing sexual happened and she just got too drunk and crashed in his room then SAY THAT.

The fact she's insisting it wasn't even his room when I'm almost certain it was is the part making me think something happened.

Would you believe her or am I just losing my mind here?
