In the middle of a group activity/ tour which we had booked to do together. Just before we left her boyfriend decided to send her a dick pic and then she spent half of the tour on her phone sexting him. Everytime i turned to speak to her she had her head down texting. I said get off your phone and she just said, this never happens so it's a priority and i cant not reply. I said I would have thought a special trip abroad with your friend would be just as rare and she said "yeah fair" and laughed it off then carried on. When she finished i asked her if she was "back in the room". I was obviously annoyed but she's so unself aware she didn't even clock that I was upset by it.
I've spoken to her when it was over and told her it upset me and she said the sexual side is an issue in her relationship so she doesn't want to miss the opportunity when it arises as he rarely ever initates anything so doesnt want to turn him down when it does. On this basis, AIBU?
