My girlfriend (20F) reacted quite abruptly and seemed upset when I (23M) brought up the idea of planning a trip with the guys. How should I handle this situation?

Subject: Seeking Advice on a Holiday Dilemma Hey everyone, I recently brought up the idea of planning a boys' trip to Portugal with my friends later this year to my girlfriend. Unfortunately, she reacted quite negatively, stating, "holidays are not for people in relationships." Just to clarify, this is a drinking holiday that involves some clubbing. I understand her feelings, especially given our age, as young people can often be sensitive about issues like cheating. My girlfriend and I have been together for a little over a year, and I truly care for her and value her feelings. However, she tends to become quite abrupt whenever I talk about going out with friends, and her reaction to this holiday was particularly strong. Last year, I went on a similar holiday without her, where I enjoyed myself responsibly and kept her updated throughout. Unfortunately, I did fall ill and had to go to the hospital, which I know must have been concerning for her. The friends I’m going with are mostly single, with one other in a relationship as well. They’ve met my girlfriend and get along with her well, and she likes them too. I've noticed that over the past few months, I've started to drift away from my friends, not engaging in group chats as much and not seeing them as often, which I completely understand. This distance worries me, and when I brought up the holiday, her reaction was to snap at me. I've never been in a serious relationship before, but I know she has been cheated on in the past. While I recognize that guys' trips can sometimes be associated with infidelity, I want to reassure her that, living in a big city where she doesn’t know anyone, cheating would be equally possible regardless of location. I’ve never been unfaithful and consider myself mature enough to avoid risky situations, like going to strip clubs, which I generally don’t frequent anyway. She doesn’t have many friends and seems to feel a bit lonely without me, which I understand. However, I feel that this shouldn’t restrict my ability to enjoy time with my friends, within reason. If anyone has any thoughts or advice on how to approach this situation, I would appreciate it. Thank you!
