She needs to go before she takes over your entire life, sips from the juices of your soul, and eventually devours your genitalia like the succubus she is. Sometimes trying to hold onto something you know isn't good for you, only makes the situation worse. And it seems she's not only involved with you, but your family, in a professional environment... Imagine how awful it would be if she put your parents business in jeopardy because she can't contain her incredibly irrational emotions. I don't think I'd be able to forgive myself for that.

INCEST!!!! Does she really think you're cheating on her with family....?
