Keeping Pure

This guy in a bar notices a woman, always alone, who comes in on a fairly regular basis. After the second week, he made his move.
"No thank you," she said politely." "This may sound rather odd in this day and age, but I´m keeping myself pure until I meet the man I love."
"That must be rather difficult," the man replied.
"Oh, I don´t mind too much," she said. "But, it makes my husband pretty upset."
