Do LDR doesn't work, ever..?

I'm 22M and like a girl (19F) very much, and she likes me as well, but we live far apart. We met on reddit a few months back, in some college related sub, and talked a lot here, before sharing contacts. Now we talk to each other a lot, and do VCs literally every day. We've met twice irl, can't exactly call it a date though. I've got so attached to her that i think i love her So recently she has been saying stuff like we don't have a future together, it will not work out, and she also said that she really likes me but don't want to date because she don't want a long distance relationship and LDRs don't work... What do i do? She said that she's not able to focus on studies properly and get zoned out while studying, ever since we started talking (i feel guilty for this) and this is just gonna get worse if we start dating. Also, she said it might be an infatuation from her side (which I'm afraid of), which might probably end in future, so she need some time to make sure that's not the case, as she don't want me to get hurt.
