Oh Idk

I have to say that my english is damn bad, so don't convict me for it :)

Soo, u can laugh if u wish, but here it is:
I'm 15 years old and girl that I like is 19 years old. I know that the age different is very large, so I really didn't expect something, but...
She is my friend's sister. We (me and my friend) are play in the same basketball team, so I met her first time when she came at our game and we are all together walk to home after that game.
After that we started to communicate in internet (like facebook, but russian), we was communicating pretty often, and one day I even came to their house (when I was with her brother, my friend), and she was there when we came, I'd say that we well communicated there too, not so much but pretty well. So after this I only saw her at our basketball games but didn't communicate with her cause she was leaving the game directly when the game was ended and we even didn't met.
But we continue to communicate in internet.
So, 2 weeks ago we had conversation (in internet) that confused me. How I said I really didn't expect something since our age difference was really large, but conversation was like this:
-Me: I really think you are ... (doesnt matter) not only because of your appearance, by correspondence with you, you seem very nice too.
-She: It's a pity that only by correspondence.
-Me: What do u mean?
She: We communicate in internet, I much better in real life hahah

Aw shit, I was a bit confused when I heard this. Does it means something?
After it we even stoped communicate a lot, because my answer was exhaustive.
Maybe it's a hint? But I need to be 100% sure about her thought to do something.. Because of the large age difference.
Soo, does it means something or not? I really doubt, since she is 19 years old.

Sorry again for my stupid english and I hope u understand me.
Yep, I'm only 15 years old, but I would appreciate if u try to help me.

Alex, your English is fine.

My best advice is to not judge someone's feelings by a single and confusing conversations. Instead, it's consistency of words and actions which tell us how someone feels.

She could be flirting with you, but don't get involved. At best, any interaction would be a casual one and you're far too likely to get hurt. Just enjoy your crush on her until you find a girl your own age

I agree with first answer but maybe here is any more opinions?
