How to exclude rows from a text file for loop

I have a textfile (file1.txt) with multiple lines of data. This textfile I'm using to copy data from a directory A to another B. My script looks if an expression is included in a filename of a file stored in A. In the directory A I grep another textfile (file2.txt) to get information (rows like [bla][0-9][0-9][bla][0-9][0-9]) that I want to exclude in my script.

set x = `grep '[bla][0-9][0-9][bla][0-9][0-9]' file1.txt`

foreach i ( $x )
    cp A/*$i* B/.
end

For example rows in file1.txt:

bla11bla11
bla12bla12
bla13bla13
bla14bla14
bla15bla15

and grep result from file2.txt that has to be excluded for the loop

bla11bla11
bla12bla12

My script should finally only use the following lines

bla13bla13
bla14bla14
bla15bla15

How can I do this?
