<human>: Condense the text into a few key points

(copied from xpost)

I've always thought I had my emotions in check. My relationships are nothing to brag about, but it's pretty consistent: a date here and there, bimonthly sex. But I've never felt anything for anyone. Ever. No real crushes, no puppy love, nada.

I met this girl through a friend (they use to go out, now they don't even talk), and we've been hanging out around twice a month. Now I've developed these unfamiliar feelings that have me thinking irrationally and physically hurting me, which I cannot make sense of :-/ when i think of her, it feels like I'm getting kicked in the diaphragm, and my jaw hurts like I've been eating salt and lemons for hours (yum). Everything reminds me of her, and I can't seem to enjoy things the same. I can't think of anything without wondering what it would be like with her.

I know she knows I'm into her. I've refrained from seeing her regularly, we don't talk much, and I've dropped a few comments here and there. But whenever we do hang out its like we never left each other and we always have a blast.

All I can think about doing is hitting her up, but I know that'll push her away. What can I do to make her realize what she means to me, without fucking things up?
<bot>: 28 (she's 26) and falling for the first time. She's a friend and I can't help but feel like she's the one. Need help handling these unfamiliar emotions without messing things up.
