maybe she had problems with violent men in her past & when she heard 'kung fu,' she just thought she wanted nothing to do with any kind of fighting... i know that's a very narrow view of what kung fu is, but then never underestimate the general public's ignorance on any kind of martial arts subject.
Some women, it has the opposite effect. They feel 'safe' around you and also like it that you are keeping up with exercise, so they don't have to worry about you having a stroke at age 50 and then they're trapped wiping your ass for you for the next 30 yrs.
you find the right match -up and all your worries will be water under the bridge.
peace
Master...Teach me kung fu.
