Irish translation

[cybergzu]

Good afternoon everybody!

Mi girlfriend left me a note in a book in Irish... Nice from her, however there's no way for me to translate it. If somebody could give me a hand, here's the text:

Is breá liom tú, agus tá sé seo ar cheann de na cúiseanna. Tá tú mar sin difriúil, tá tú mar sin leat.

Thanks a lot

Ps: If somebody know a site that could help me learn a little bit this language, it will be greatly apreciated!
