//she compared to it once as almost lowkey cheating as she believes those are experiences you should share in a relationship like she might have a point? esp seeing how it would be me and another female coworker i am sorry, but no, she doesn't have a point, it is short trip with coworker, no matter man or woman, especially if you are friends, idk if that is business trip, but, i think she is putting some shit on you which she shouldn't, that is just petty. so does that mean you should never travel anywhere since she cannot go with you? i get it, i would feel guilty i cannot travel with my gf/bf, but, i would make sure she got every piece of info and photos and videos to feel included. Short travel shouldn't be consider lowkey cheating if your relationship is strong and stable as you claim it is
you're right it's pretty much no traveling anywhere ever (except for work) so idk maybe it's not as strong and stable as I thought
