I met this girl a few weeks back (posted a little about it). I thought she wasn't interested, but we ended up meeting up one night and I went back to her apartment that night. We didn't have sex (she told me while we were making out outside her place "i'm not having sex with you tonight"). Fine, I'm not too worried about that right now. But we slept together on her couch (roommate). I guess like a week later we went out again together, a couple of my friends and a couple of hers. Slept over again, no sex. But the sex isn't my concern here. This past Monday night she invites me over to hang with her roommate and roommate's boyfriend, just us 4. It went well and whatever, we went to go sleep in her room. All good. Last night we go get dinner and then go for a long walk, stay at her place again. She seems to like me, but I definitely like her. Here's kind of the problem.

I think I already like her too much. I almost don't know how to explain it. But my confidence has grown a lot lately, and I feel like I'm reverting back to my lame old trying-too-hard self when I'm with her instead of being loose. I left her place earlier today around 11:30AM, and texted her later in the day. She responded a few times, but hasn't to my last one like 2 hours ago. I'm already getting stupidly nervous that she's over it or whatever because of the no answer. I can't stop myself from thinking and worrying about it.

edit: man, you guys are really helpful. i said this in a comment but this shit is therapeutic. thanks for all the incites/help so far.
