What does passive されてはねぇ means?


> 彼に迫る上であなたは利用価値が高い
>
> こんなところで脱落されてはねぇ

"I can't allow you to be desert me"? or is ね particle? Why the passive?




It's a suffering passive construction followed by ては/では.

  * 脱落する  
to drop out

  * 脱落される  
to _(unfortunately/annoyingly)_ drop out  
([suffering passive](https://japanese.stackexchange.com/a/50432/5010))

  * 脱落されては  
if you drop out  
([ては for "if", indicates a bad result follows](https://jlptsensei.com/learn-
japanese-grammar/%E3%81%A6%E3%81%AF-%E3%81%A7%E3%81%AF-tewa-dewa-meaning/))

  * 脱落されてはねぇ  
if you drop out, you know...  
([ね as an interjectory particle meaning "you know (what I
mean)"](https://japanese.stackexchange.com/a/42321/5010))

> 彼に迫る上であなたは利用価値が高い。  
>  You are valuable in approaching him.
