Om Shakti,
I believe I read somewhere (the course or maybe another book on Feng Shui) that if all or many of the children in a family have problems with relationships, you should look at the parents' Feng Shui. If the parents' home has things out of place for good Feng Shui, such as wrong element in relationship sector or even a Conflict Star for 20 year period that is uncured, this will affect the two generations after them.
You may want to check your parents' home for Conflict Stars (especially long lasting ones, such as the 20 year star), and check their general relationship sectors to be sure there is not a color or an object in those places that suppresses good chi.
