Lau teine pele translates to: Your dear girl. La'u teine pele translates to: My dear girl.
I feel that what you are saying is: "Alu e fai lou aiga ma lau teine/tane". If this is the case, then the translation would be: "Go have your family with your girl/husband". I got thrown by what you wrote "taine", which I thought could be, "teine", which in the sentence you gave, means girl (romantic way) or girlfriend. But if you meant "tane", then that would be "husband". That was the reason why I placed a slash between teine/tane or girl/husband. You just choose which one of the two you meant.
