I agree with above. If my STBXW comes into my house, it is on MY terms. As a gesture of goodwill, I have invited her into my dining room on children's birthdays - for the children's sake. Outside of that, I will not have her in my home. It is not petty or bitter. I don't want her to violate my personal space. Also, I don't trust her - she has a proven track record of being a liar and thief. Also, what happens to her on my property is my responsibility and I don't want to be liable for anything. It is GOOD that it makes you uncomfortable. That is a protective reflex.
