<human>: Can you succinctly summarize the text in 1-3 sentences?

So I have been talking to this girl over Facebook over the last month and regularly this past week and decided to ask her out to coffee.

I was really nervous before seeing her and was afraid that I wouldn't know what to say or hold a conversation with her.

Anyway I picked her up we went to coffee and it was really nice, we had heaps to talk about and the conversation flowed much better than I thought.

I think we both discovered that we have a few things in common but also a few differences in our likes and dislikes. I find her attractive but I am just uncertain after dropping her home.

I though I would be feeling really happy driving home but I felt so weird, almost like I didn't feel great but didn't feel bad. I was in a trance.

I've never had a serious relationship either so I'm not sure if that has anything to do with what I'm feeling.

I sort of sense that she might have a crush on me, as she texted me when I got home from dropping her off.

Are my feelings normal or what the hell is wrong with me? I guess I built up my emotions way to high before seeing her, it was nice but I just don't know how I feel. 

Also this is a bit different to how I usually become attracted to women as I've developed this crush over texting (she went to my high school, we never talked and it's been 3 years since that). Does that have something to do with it?

Any advice would be great
<bot>: Went out with this girl but unsure of how I feel (this could be my first relationship) is it all in my head?
