while IFS= read -r line; do grep -q "$line" file2 || echo "$line"; done < file1

And if you search file1 entries only at the begining of a line and terminated by a coma:

while IFS= read -r line; do grep -q "^$line," file2 || echo "$line"; done < file1

awk -F"," 'FNR==NR { _[$1]=$1; next} ! _[$1]' file2 file1
bbbb
