So here's the deal. Me and My Fiancee can't stand his brother's "Fiancee". He is my FI best man since they are brothers but she is not invited. She has dissed there side of the family since day one and thinks she is better than everyone and knows everything. I can't stand people like that. Then what made me dislike her so much is she dissed the way my FI proposed and said it was lame. He did it in front of practically the whole town of austin, tx. He just gave her a ring to shut her up. Then the final straw for the whole family was there dad caught her kissing all over there roommate. Then she had the nerve to call him a liar even thought they were 10ft away! So needless to say the whole family doesn't like her but he is such a pushover he stayed with her. So my fear is that she will try to show up the day of the wedding as a guest. So would I be wrong to hire someone to stand at the enterance to make sure she doesn't come in?
