I would tell hubby that it is completely out of order inviting her in, what signals does that send out, if it were you doing the entertaining how would he feel? Although I absolutely hate confrontation I would let this woman know not to cone round anymore whether you are in or out. She is manipulative and knows what she's doing alright, you are better off without her. I agree with what Anniemac said, however, I would be at home for a time and answer the door each time, never invite her in and say can't stop hubby and I are in the middle of something and close the door, she will probably get the message before the talk with her and move on to another.
