I know this girl in greece.
That I fell in love with
This summer I went greece and now I love her even more but I don't think she knows it.
And I'm in the uk and she's in greece I've got her msn.
But when I'm without her it feels like my heart is being torn apart can't sleep can't eat can't get her of my mind
I really care about her
Should I tell her I love her??

What have you got to lose.

Not telling her seems to be making you miserable so what harm can telling her do.

Just be wary that long distance relationships are very hard work and rarely successfully.
