<human>: Can you condense the text into a few key points?

So me and my GF both planned on going to Gulf Shores during Spring Break with some of my fraternity pledge brothers and best friends.

Well today she told me she didn't have the money and couldn't go. That's where the problem arises. I do have the money to go, and I still want to go, so I told her that.

We got into an argument and she said I was being selfish and only thinking about myself because I'd be "leaving her all alone while you go out and have fun." 

I told that I wasn't going so to end the argument, but should I feel bad for wanting to go even though she can't? Am I being selfish? Should I go?
<bot>: girlfriend can't go to spring break, i can, she doesnt want me to go. I tell her I still want to go if she doesn't come, fight ensues. Should I feel bad?
