Is OTHER wrong in the post ? POST : I have two best female friends, sisters, that I've known since childhood.  Three years ago they moved from California, where I live, to Texas. But nevertheless we've stayed good strong friends over long distance. And ever since they moved we've been talking about meeting up once we have the time and money. 
Last year, I got a girlfriend.  We've been a good strong couple and for the most part I'm satisfied with the relationship. However, I've told her of my plans to visit my best friends and she absolutely refused to let me go.  That was the angriest I'd ever seen her. 
That was six months ago and recently I've come across the money and time to make this trip in July and have fortunately got my girlfriend to relent albeit very reluctantly. I've purchased my ticket and will be staying with my female best friends for two weeks. 
Although I can't see I've done anything wrong, I just have a nagging in the back of my head. Even tho I've told her. And even tho she's relented. Am I the asshole for wanting to leave my girlfriend and reconnect with a couple of friends for two weeks?
