We're have a very small wedding...immediately family and grandparents only in July. My younger brother has had a tempestuous relationship w/ his wife(long story, lots of drama, but she's had a boyfriend for a lot of that time while still be married to my brother), and they've been separated for a year and a half. Anyways, I just found out that they're trying to 'work things out,' but there's no way that I want her at my wedding. She starts crap and causes drama anytime she's around the family for even an hour or so. We're going to be at a B&B for a weekend, and I think she would ruin it.
Would it be completely inappropriate for me to not invite her? I just know she'll try to ruin it somehow...
