<human>: Can you condense the text into a few key points?

I'm 24(F) and he's 27. I just moved into a really small town a few weeks ago. I met this guy through a friend of mine that doesn't live too far from here. I immediately felt attracted to him as soon as we met. The attraction stunned me. It kind of shut me down. I just don't know what to say half the time out of fear of sounding stupid... which is ridiculous because that's not me. I'm usually an outgoing, pretty talkative person. It's been a while since I've been in a relationship and it's like I've lost how to deal with the whole flirting, chase, whatever happens pre-relationship. I know he's interested in me because he's complimented me many times, asked me out on dates and we've kissed and cuddled. although, he leaned in to kiss me goodbye when I was leaving the other day and I kind of just got really nervous and walked away.... leaving me feeling like an idiot for doing that. I'm interested, but I also don't want to seem too interested since we're just getting to know each other. Expressing my feelings towards someone is a hard thing for me to do. I know he knows that I obviously am somewhat attracted to him or else we wouldn't be cuddling and kissing but how can I get over my awkwardness? How long can I get away in this shell I'm in before he decides he isn't into me?
<bot>: New girl in town, I like a guy who likes me but he makes me too nervous to even speak my mind without sounding like an idiot. How can I get over it and how can I make him stay?
