Love / English guy falling for a Polish girl at work [14]

Hi there, im new to this forum and wanted some advice/pointers off people who have possibly been in this situation.

Basically, iv started working at a factory in UK, were alot of polish people are employed. Iv been there about 2 months now, and there is one girl iv fallen for. I really like her and im convinced she does me, we always make eye contact when we see each other, and passing in the corridor etc, its like more then a normal workmate would have, and she never says morning to me, but she will to other people, but yet continues to stare at me etc. But as usual, theres a complication, the fact shes polish and im english. Id love to just say something to her in polish and impress her but i dont know theyre language and she speaks little english.

What would your guys advice be? Try forget about her cos nothings ever gonna happen (realistically) or maybe someones got some phrases i could say to her. Im honestly clueless, all i know is my heart races when i see her, and id love to some how tell her i like her, whether or not she felt the way.

Thanks everyone
