Hurt by her Hawaii trip plans with her girlfriend

I can't help but to be hurt after my girlfriend told me she was going to plan a trip to Hawaii with her girlfriend along with other trips (Australia, New Zealand). This is after I had suggested that there were some cheap flights to Hawaii some months back and maybe that was a trip we could consider. She said that she wasn't interested in Hawaii. When I brought that up a few days ago when she told me about about her trip plan to Hawaii with her friend, she said "well, I guess I am". Meaning, I guess I am interested in a Hawaii trip. But she still insists that Hawaii is really not something she was ever interested in. To be fair, she has traveled with her friends for years. She just recently came back from a cruise (not with me). Went to Cancun earlier this year (not with me). We went to Europe earlier this year by the way. She is going to Cancun again in February (Not with me but with a different friend. Not the Hawaii friend). But I still can't help but feel that she would rather travel with her friends. She goes on these, what I would consider should be romantic trips but just not with me. I really don't feel that she is going on romantic trips with her girlfriend but they would be if the trips were us together. I can't help but to feel hurt and I told her so. She said that "does she want me to just stop traveling with her friends?" No, but the whole Hawaii thing has me stressed. It's been a few days now and I can't seem to get over it. We had another conversation about it and I told her I was still upset. She said she didn't know what to do. She didn't want to disappoint her friend. (I guess it was better to disappoint me). I relented and basically said she should go with her friend. We have been seeing each other for 3 years. We don't live together but love our time together.

Francesco, you're correct, your GF doesn't have the need to travel with you, instead she would rather travel with her friends. Her actions are telling you that while you guys have been together for 3 years, she's not that into it and only has time for you when she needs the time with you. After 3 years, you should know what sort of a person your GF is and if she doesn't share your values and share your need to be together, then you know what to do.
