Took a girl on a trip for 4 days, paid for everything obviously staying together in a hotel room just us 2.

We've been hanging out for 2 months and fucking alot/talking, but not dating. She's kinda shy, from the countryside, pretty sure has low count, and not a club girl.

We went out to the bar, had some drinks, and when I get back from the toilet a guy was sitting there talking to her. I dont really mind, I say hey my name is and you wanna beer man? He gets super nervous and walks away.

Say "that was weird" to her, we laugh and I shrug it off.

3am she says he was messaging her and I jokingly go "uh oh gave him the digits!" And walk away ready to just forget about it, guess it's not a big deal cause were not dating.

She says "no he already had my instagram" and I'm so confused. How does a random guy who came up to you at the bar have your instagram already?

Turns out while on this trip with me she's on tinder swiping (weird but again I guess whatever), and turns out he was from tinder and he asked if she wanted to hangout, and she says yes im at this bar come meet me. She showed me the messages. Pretty tame, but nonetheless she has rando tinder guy come meet us, who obviously wanted to fuck as he left as I sat down.

I thought it was pretty disrespectful, but am I just being butthurt?

For instance there was a girl at the bar, while my girl is grinding on me, there's another girl that we dont know grabbing my dick over and over, trying to take me from her. I keep laughing and not going for it, because I'm on this trip with that girl.

Maybe traveling with a non gf is just bad logistics?

Edit: thanks guys, I wanted to post this as I wasn't sure if my logic was off. Looks like I was on target.

I've had many girls do bullshit involving other guys and usually err on the side if eh if I'm not dating idc if she is flirting, texting, etc. I'm doing the same anyways. But it made me mad she would do this while I'm paying for the flight hotel food drinks everything and has the guy fucking show up.

At the airport on our way home, having her take a separate taxi to her place after I call it quits with her.
