This started to sound so complicated I had to dig the frame break char myself ;)
Just create a text filter (can be accessed in Get Text's file open dialog). If your paragraphs are separated by a single line change create a "replace" filter and mark it to be regexp (the lonely checkbox in the filter row). Then you'll replace '\n' (without the quotes) with '\x001B' (again without the quotes). This will give you properly split text. Now you'll only need to link the text frames.
