Okay so the background. About 2 months ago by FMIL asked what the plan was for my bridal shower. I told her that my family would be throwing it and that she would be invited along with anyone she wanted. She kept saying I won't do that I need to contribute. I ask my FI to tell her that its really okay, my family wants to throw the shower and invite my future family and friends as a way of welcoming them. All of a sudden my FI is flooded from nasty calls and texts from his father, mother, and sister about how my family is so awful and rude and uninclusive. I am upset about this because up until that point I thought things were going well. His mother demands that her name be put on the bridal shower invitation (even though she will not be hosting). I call his mother and let her know that I dont want her to feel left out but it will still be a shower hosted by my family and she is invited to go. She is extremely cold and doesn't say anything other than thanks for calling. So my family goes ahead and orders the invites and I ask his mom for her list. She only invites 3 people (does not include any of his family, all of whom we see at family gatherings). I ask her if this was a mistake and she says no. So FI calls her to find out why his side of the family isn't invited she says because she is "embarrassed" and "humiliated" inviting them to something she didn't contribute to. I don't get how this is embarrassing especially since she had no problem inviting her 3 good friends. So I am upset at this and so is my FI. We are just going to invite his family (aunts and one cousin) without her approval.
What do you think about this? Is there anything that I can do? I have tried to talk to her and make her feel more included but I get no response other than coldness.
