<human>: Apologizing ahead of time here because I feel like my mind is going in 3 different directions. So, I'm a college student that has recently transferred to a larger school in a new city. I have been dating a girl since October and it has been... good. I enjoy her company most of the time, but I find our lack of common interests and hobbies slightly irritating at times. For instance, she's very interested in collecting things like bracelets and bags, while I am into sports and fitness.

BTW, we have not said the L word yet, if that matters.

Now, there's also a girl at my Crossfit gym. I have been smitten by her since I first met her. She's pretty and intelligent with a great career. She's also closer to my age (24). We've been talking more lately and it does seem like she's flirting with me. I honestly have no idea if I could have a relationship with her, but she's a nagging presence in my head.

I feel like I can't dedicate the emotional attention that my girlfriend needs with school and work taking up most of my time. I can tell she needs someone that's more emotionally available. 

So, here is my question. Do I stick things out with the current girlfriend or break it off? I feel like a prick for even considering other girls but still have feelings for my current girlfriend. I have suffered from self-doubt in the past over breakups, and I don't want to throw away a good thing for something that doesn't exsist.

Can you summarize the given text in a few sentences?
<bot>: I have a good relationship, but I don't feel like I'm as into it as my girlfriend is. Deep down I think I know what I have to do, but I need someone to talk me through this.
