Data Filter copy Paste

I have a spreadsheet which has data in the following format

FILE_STARTxxxxxxxxx
111moneyistheking                   money joker
12312342453534
123monkey love packages
FILE_STARTxXxxXaidoa
4564543love
666pokerking
888love
FILE_START1231231
445joker
FILE_START6666
4848864

I would like code which looks through each of these rows, if it contains the word "love" then extract that set of file.
a file starts with the word "FILE_START" and ends when the next "FILE_START" is present. So the "extract" must contain all rows inbetween the two "FILE_START"s if the word "love" exists in between the two "FILE_START"s...

The number of rows in between each "FILE_START" can vary.

so with the above data in say sheet1, i would like to following output in sheet2

FILE_STARTxxxxxxxxx
111moneyistheking                   money joker
12312342453534
123monkey love packages
FILE_STARTxXxxXaidoa
4564543love
666pokerking
888love

I hope this makes sense?
