<human>: M33, met a girl F22 while we were both on vacation.  We spent one day together, and I was planning on leaving for my next destination when I decided I could stick around and spend another day together.  It was really quite lovely.  If it's relevant, got to 3rd base, no sex, she seemed uncomfortable going further and I respected that.

I'd definitely see her as girlfriend material if she didn't live thousands of miles away.  Unfortunately, she does live very far from me, and I am not good at LDRs.  Doubly so at the moment since I got out of a serious relationship just a couple months ago.  I could definitely see myself traveling to where she lives in a few months when I next have time off, and she might be in my area several months from now.  Even so, I don't want to commit to anything serious with someone I just met who lives so far away.

I was clear when we were together that I liked her and liked being around her, but that it wasn't something long lasting.  I didn't want to lead her on in any way.  For example, she asked what it meant that I kissed her, and I said I'm happy to see you and I enjoy your company, and she said that answer was a little disappointing.

Maybe I should have backed off when she said that, but I didn't... since then, she's sent me a couple emails saying she's feeling very sad now that I'm gone.  I don't want to give her false hope for the future, even though it would be nice, and I hate thinking a girl I like and care about is hurting.

Any advice?

Could you distill the essence of the text into 1-3 sentences?
<bot>: hooked up with a girl I just met last week while on vacation, now she wants more than that and I can't give it to her.
