So basically my friends and I enjoy travelling a lot. We’ve been many places together, both domestically and abroad. They recently found some cheap tickets to Australia and pulled the trigger to go there at the end of 2019. 
Here is the issue. My girlfriend and I spend a lot of time together. Probably 5-6 days a week. I’m happy with this and everything, but we have had issues in the past where she gets upset that I make plans with other people because she wants to spend that time with me. For the most part, we get over them and she apologizes for being too controlling of my time. Early in our relationship, I went on a trip abroad with a friend of mine and it was kind of hard on her to be apart from me even though we did a really good job of keeping in contact and talking while I was away. 
Now, we have already taken a few trips together, but nothing internationally. We talked about maybe taking a trip abroad, maybe to Europe sometime in the not so distant future. She mentioned that she’d really like to go to Australia or Europe, but we had talked a lot more about going to Italy or Spain. Now, when my friends mentioned that they were ready to make plans to go to Australia, I wanted to jump in on it. 
The problem is that my girlfriend got really upset that I wanted to go to Australia, a place she specifically also wanted to go to. The thing is this is a trip that was initiated by my friends. I would love to go with her to Australia, but when its just her and me. If she comes with me and my friends, I fear that I will only spend time with her while we’re over there and I won’t really get to share the experience with my friends the way I would like to. I tried to compromise with her and promise her that we can go there another time, or we can pull the trigger and go on some other trip that she wants to go on, just the two of us. None of that worked and both of us were upset because she wanted to go with me to Australia, and I wanted to go to Australia with just my friends. I am really trying to be compromising and finding the best way that we can both be happy.
After fighting about it for about a day, she had some other plans and we split apart for most of the day. In the evening I saw her again and she apologized for being controlling of me and in her words “just because I can’t go, doesn’t mean I should stop you from going.” I felt a lot better after that and even bought the tickets. But now, a day later, I feel really guilty of the whole thing. I don’t know if I was in the right or not, and just want to know if I’m being unreasonable about the whole situation.
