When is it acceptable to kick out a member of the wedding party? The BM has been FI's best friend for years, but he has recently started groping me whenever we are around him. FI is furious and wants to kick him out of the wedding and just never associate with him again, however things are complicated by the fact that the BM is also FI's BIL and I am afraid that this will cause a permanent rift within his family. FI wanted to confront him about the behaviour right away but I felt that I could handle it and just protect myself from him but have been unable to (he is quite a bit older than I am and is very large) and it has now escalated. I guess I am just looking for some general advice for how to go about this in a way that will least hurt the BM's wife (FI's sister).
