Au pair life

I am working as aupair in the UK. I don't like this country, but I think that living here is the best way and quickest to improve my English?
I work with three children, who have one, two and three years old. I like the job and the family. They are so nice, but I miss my family, my boyfriend and also the good weather of Malaga.

Au pair (two words) life

I am working like as an au pair in the UK. I don't like this country, but I think that it living here ("it" is a vague word) is the best and quickest way to improve my English faster. (taking out "faster" and using "best and quickest" instead is NOT an essential correction, but it helps the sentence flow better, and sound more natural to a native speaker)
I work with three children, who have are one, two and three years old. I like the job and the family. They are so nice, but I miss my family, my boyfriend and also the good weather of Malaga.

Thank you for sharing, and I hope you become better acclimated as time goes by. Good luck! :)
