It does sound like you're not that invested in the relationship, and it could be that you're just not attracted to her. Even if you haven't been together that long, over a month should be enough time to develop feelings and know that she is who you want to be with. Don't be afraid to consider breaking up if you're not excited about the relationship. You need to do what makes you happy, and if finding someone else would make you happier, then go for it. I've dated people who I decided I just didn't have strong feelings for and so I ended it, otherwise I figured I was just wasting both of our time.
