Have you ever had a small business jeopardized by a family member or friend?

[Shortie]

When it comes to doing something for yourself like a business, all too often, family members or even friends can get jealous of what you are doing or even if you are succeeding. This doesn't happen to all but when it does, they usually try to jeopardize your success in any way possible to make it so you no longer succeed.

Have you ever had a business that a family member or friend jeopardized? How badly did this affect you and were you able to pull back from their acts?
