<human>: I just started dating her a few months ago, and before her I was single for several years. I wasn't trying to date anyone in that time frame either, I am perfectly happy on my own. In fact, I feel like sometimes I prefer it. 

I signed up for Tinder a while back as a "I got a new smartphone, lets get on all the apps that I've heard about" bonanza. It was fun for a while, but I only had a few matches. First one I went on a date with, didn't pan out. Second match we hung out for a few months but she moved away. The girl I am currently dating is match #3. 

So #3 and I start talking and we begin seeing each other exclusively a few months ago. We agree to be referred to as each others SO and use the terms "boyfriend" and "girlfriend" though I dont really care much about labels. Now, she is away at school and I'm feeling more and more like I would be better off alone because I'm not happy in this relationship, but at the same time I'm not exactly unhappy. 

I genuinely feel nothing. I'm not really attracted to her, but then again I'm borderline asexual I fear. I think I just fell into this because it was there. Now she has hinted at using the dreaded L word and my thoughts on that and I am nowhere even close to that level. I feel like since I have hardly any feelings for her, and she has much stronger feelings for me, its unfair somehow. I feel like being alone again because I feel bad that shit like this happens and I hate hurting people and I'm fine alone. 

How do I enter a mature conversation about the gaps in our feelings without coming off like an asshole?

Can you condense the text into three sentences or less?
