<human>: Met on OKC, chatted online for a week; got along super well, she's mega nerdy and her picture was cute. I asked her over, and the night lead to the bed. Was a lot of fun, and my first real non at-a-party-hookup. 

She came over again about a week later, was a lot of fun, but I suddenly felt weird about her being there. I don't like sharing my bed -- I have never been able to sleep with someone else in my bed (I like to sprawl out, and I get conscious about snoring/breathing).

She started to seem less attractive to me. I have been feeling, though, that this is not an indication of actual attraction, but of my crippling fear of commitment. Maybe I am self-sabatoging so I can go back to the comfort of alone? This feeling of being unsure of whether or not I was attracted to her has continued to persist. In the moment it is fun, but afterwards or during post-sex cuddling I cant help but have my mind wander to 'when is she going to leave'. 

Last time I saw her, after sex she told me she loves me. I didnt know what to say back. I fear things are moving just so quickly, and my natural response is to just try to back out. I don't want to hurt her, so I don't want to say 'I love you' back, because all progress will make a split worse and more hurtful for her.

Condense the text into a few key points
<bot>: I can't tell if I'm not attracted to her or if I am just bewitched by a fear of something real, of having to commit.
