Perhaps I could have been more specific at the outset, but explaining what you would like the code to do when you are not very sure yourself how to go about the task is rather difficult! 
use warnings;
use strict;

while (<DATA>)
    {
    chomp;
    my @sentences = split /(?<=\.)\s*/;
    
    #print '>', join ("<\n>", @sentences), '<';
    foreach(@sentences){
        print "$_\n";
    }
    }

__DATA__
Hello world. Hello Bretheren. Goodbye spaces. All I really want are se
+ntences.

Which prints:

Hello world.
 Hello Bretheren.
 Goodbye spaces.
 All I really want are sentences.


Your code

>Hello world.<
>Hello Bretheren.<
>Goodbye spaces.<
>All I really want are sentences.<

I would like:
 
Hello world.
Hello Bretheren.
Goodbye spaces.
All I really want are sentences.

Your code print '>', join ("<\n>", @sentences), '<'; does exactly what I want except for the > < I would like the data without the space to left after the first line.
