Why am I sad about this?

So I met this girl on Reddit. We’ve been talking for two weeks now. And she has the girl of my dream’s personality. Like I never met anyone like her. We met because I made a post about my failed attempts at finding love. And she had similar experiences. So we both wished each other luck with finding love. And a few hours later, I thought of her. Like fuck it, let me just see where she’s from. And I messaged her not thinking much. But she was happy to see that I went back for her. So we started texting for three weeks now. And we have almost everything in common. Like it’s insane. But what makes me feel like shit is that she said she’s not looking for anything romantic. So I agreed. But since getting to know her more, I can’t help but have some sad thoughts. I knew she lived far away from me, and that we wouldn’t become anything serious. I even wished her luck in whatever guy she gets because he would be lucky, but I just have some tears going down my face as I’m talking about this now. And it’s not stopping
