Translation anyone??

Who can translate this into spanish...but where it makes sense.

You can only push a girl away for so long until she walks out of your life on her own. So be careful and make sure this is what you want because once she turns around she isn't...

coming back.

Solo tu puedes empujar una nina fuera para tan largo hasta ella corre afuera tu vida en lo suyo. Tan Esta cuidadoso (y) haz seguro este es que tu queres porque el momento ella deje no esta volviendo.
Im pretty sure this is como tu dices (how you say it) but Im still a student (a very devoted student) and you should try babelfish to check it out. Though babelfish uses word to word translations and that isnt how correct spanish is spoken. Spanish is littered with phrases that dont make sense in English but thats the way to say it in Spanish type situations.
But for pronunciation remember to roll your R's and that your J's actaully sound like H's, and you'll be fine!
If the 'y' shows up as why, just remember its pronounced 'ee' and not 'why' because it wont let me post it as its actually spelled!
