I'm going to make this as short as I can, although there is lots of backstory that may or may not be relevant.
My FI's mom passed away last month from cancer. FI is very sad, obviously. Before FMIL died, FSIL called FI and told her she would be the administrator of the will. FSIL scheduled the memorial for July.
A couple weeks after FMIL died, FSIL texted FI and said , "contacted the lawyer who wrote the will and he hasn't call back yet. Found a lawyer in [another city on the other side of the state]. She wants me to find out from you if you will be ok with signing off on getting your 40% less fees." FI's response was basically "why are you texting me about this?" She later apologized and explained that she was "ready to get all this started."
FI then got a letter from an annuity company stating he is a beneficiary of such and such policy of mom's and blah blah blah. FI asked FSIL what this letter was about and what he was supposed to do about it. FSIL got upset and said, "that annuity is supposed to be for me, mom said that I'm getting that one and you are getting the other one." She said that her mom told her that she wanted FSIL to have the larger annuity and for FI to have the smaller one. She then called FMIL's boyfriend who got really pissed at FI and "said a lot of bad stuff about him" because apparently "they have underlying issues" that FI knew nothing about.
FI was blind-sided, I think, by the fact that this was even being discussed so soon after FMIL died and before the memorial. He basically said, "if it turns out that was mom's wishes, we'll work it out." She took this as him offering to give her money or something, so she later called and said, "Billy boyfriend is so glad you decided to honor mom's wishes." At that point FI told her that he wasn't discussing any of it anymore until after the memorial.
Turns out both the annuities are 50/50 between FSIL and FI. FI emailed FSIL and explained that this made sense, that this is what FMIL would have wanted, that she wouldn't want them arguing about money, that he loved her etc.
FSIL sent him a nasty text saying, "I know what mom's wishes are. I'm not going to lie for you, if that's what you're asking." So FI spouted off with an email asking for details about why she is so upset and why apparently Billy boyfriend is so upset. He was pretty much at the end of his rope and wasn't super mean, but he did point out that she was the one who got all the money talk started before they so much as had a funeral or memorial.
So for whatever reason she called me because FI was at work and she wanted to work it out or something. And I stupidly talked to her about it. I really wish I had just said this is none of my business. We didn't argue or anything. She just went on and on about how she doesn't care about the money, she doesn;'t understand why FI is so upset, FI hurt her feelings by implying that all she cares about is the money, etc. I tried to just repeatedly say that they shouldn't be fighting over money and that this is ridiculous and that I can't even believe this is going on. She tried to say it was Billy Boyfriend who was upset about how the annuities were split up, etc. She said that mom's lawyer was supposed to change the beneficiaries and didn't and that Billy Boyfriend was there when mom told the lawyer this. I just explained that FI is hurt and that they shouldn't let this fuck up their entire relationship.
She said that she is fine with things being the "way they are on paper" but that FI needs to call and make things right with Billy Boyfriend.
FI is very, very, very upset and hurt. At first he thought she was being honest but now he thinks that be is being manipulated and that FSIL is throwing it in his face that she was mom's favorite. He is so upset with her that he is saying he doesn't want to see her, doesn't want to go her wedding next weekend, that I shouldn't go to her bach party tomorrow, etc. I know he will cool down and we will go to her wedding and be happy for her.
I guess the advice I need is more how to support FI through this because I can't say anything to help him understand it or to make it better. I kjnow I need to stay out of it, although she brought me into it which sucks. I still should have told her I'm not going to talk to her about it because it is none of my business.
I'm really sad that they are acting like this.
