Kim,
You have a family and I respect that. And respect their opinions. But this is not a request for a poker game, a night out to a male review at a chip-n-dales club, or anything that costs money. Your safety comes first and foremost. And they need to recognize that this is a means to an ends.
Quite simply put, you have several options.
1) Just deal with it (not a real option)
2) Your family give you the benefit of the doubt and allow this to take place.
3) You remove yourself from the house for a period of time.
