Why are you in a relationship with this woman? I'm not trying to be snarky; I sincerely am not following why you're choosing to be with her.
I understand that people don't always admire or endorse 100% of what their partners do, but usually those things they find odd or grating are relatively minor, and they can identify many other lovely qualities that make up for the unappealing ones. I'm not sensing from the way you write about your girlfriend that you like her very much. What do you two enjoy doing together? What is her personality like? How did you meet in the first place? As an outside observer, it just seems kind of weird reading you write about dating someone for a few months when you seem to hold a mild disdain for her.
