Wanna talk about it ?

Women will always conflict with windsurfing and want to restrict it. It's called "control", or "nesting" for the politically correct. It always starts with "I understand it's your sport, I never want to interfere, etc." Next thing you know you end up painting walls and decorating the house - at her taste of course.
Worse: if you manage somehow to teach a sheila *and* she takes to it, then she'll dump you anyways.
Ya need to find one that has an equally taking, regular sport activity, tennis, whatever. Then she'll understand you and give you time and space. Macrame, going out with the girls, skiing twice a year and beaching don't count.
Did you want other advices here ?
