Por mi, como si vuelva a su tierra

Por mi, como si vuelve a su tierra
 

I came across this quote in a Spanish drama. It was meant to meant to mean, as far as I'm concerned, she should go back to her land (country). I would never have understood this phrase out of context. Is this a phrase that is commonly understood?

Without any context, I don't know if anyone I know would understand it. :thinking:

With that meaning, I would think of:
- Por mí que se vuelva/regrese a su tierra.
- Por mí, si se vuelve/regresa a su tierra, es igual.
