My Mother and my sister (who is my maid of honour) are jointly throwing my bridal shower, my mother does not like my FMIL (and neither do I) mainly because of the way she treats my fiance and I and hurtful things she's said, my FMIL is a very negative person who loves to complain and likes to always be centre of attention, my mother refuses to invite her to the shower because she says she will ruin it. however I would like my fiances two sisters (who live out of town) and his grandmother to be invited, but I know this is going to cause a whole bunch of drama and I don't know how to bring this up with my fiance or what to do about this!!!
