Love / I fell in love (with a Polish schoolfriend of mine)... How to say I love her? [31]

Yes... Its from one year that i felt in love with a schoolfriend of mine, she's polish, at the beginning we didn't like each other a lot but now we started be good friends, the problem is that i don't know how to tell her.

She's very particular, she appear cold, she say she hasn't feelings for no one, she's very very particular... I know i'll appear pathetic but now, after one month that i don't see her more because i'm working in a far country for the whole summer and i'll meet her just when i'll be back to school, i want to tell her what i feel... The problem is that i don't really know how she'll take it... Any advice? How to say "i love you" to a polish girl? :D
