The standard input to your loop is redirected from file.txt, so both read commands in the loop are reading from that file.

If you want to have the outer read read from the file and the inner read read from the script's standard input, you can try something like:
Code:
#!/bin/bash
cont=0
while read line <&3
do	if [ $cont -eq 5 ]
	then	read -p "Press Enter to continue..."
		cont=0
	fi
	printf '%s\n' "$line"
	cont=$((cont + 1))
done 3< file.txt

or, if you want the inner read to read from the process's controlling terminal, you can try something more like:
Code:
#!/bin/bash
cont=0
while read line
do	if [ $cont -eq 5 ]
	then	read -p "Press Enter to continue..." < /dev/tty
		cont=0
	fi
	printf '%s\n' "$line"
	cont=$((cont + 1))
done < file.txt

NAME

       line - Reads one line from standard input

SYNOPSIS

       line

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       line:  XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS

       None

DESCRIPTION

       The  line  command  copies one line, up to and including a newline, from standard input and writes it to standard output.  Use this command
       within a shell command file to read from your terminal.	The line command always writes at least a newline character.

NOTES

       The line utility has no internationalization features and is marked LEGACY in XCU Issue 5. Use the read utility instead.

EXIT STATUS

       Success.  End-of-File.

EXAMPLES

       To read a line from the keyboard and append it to a file, enter: echo 'Enter comments for the log:' echo ': c' line >>log

       This shell procedure displays the message: Enter comments for the log:

       It then reads a line of text from the keyboard and adds it to the end of the file log.  The echo  ':  c'  command  displays  a	:  (colon)
       prompt.	See the echo command for information about the c escape sequence.
