TLDR Below

So I messaged this girl over OKC a few weeks ago. And we messaged back and fourth for about a week before taking it off line. I offered it, and she sent me her number.

We started texting and we hit it off, and over the next two weeks of texting we discovered so many interests, and things like sexual compatibility is about 99%, which is really high.

Since then, now I do want to meet her, but she says she can't wait to meet me, and she wants to be my girlfriend and such.

I guess my question about all of this; Is there a way to know if she is really in love, or is this infatuation?

Can there really be love at first sight? Or am I just being skeptical?

We talked about meeting at her house, and she invited me over to her house for a first meeting, and I'm somewhat hesitant. I mean I do like her, but I'm torn as to the idea of meeting up for a first time job as her house?

TLDR: messaged a girl online, we hit it off, she has said about everything except that she loves me. And wants to meet for the first time at her place. I feel like I've known her for years, even though it's been a few weeks.
