Brother not respecting no-contact with mother
TW: sexual abuse (no details)
My (34F) wife (34F) asked me to make this post for her.
She was sexually abused by her mother as a child. Like with many abuse victims, she didn't contextualise what happened as "abuse" until much later. I won't go into details about the abuse she suffered, but a part of it relates to her mother having an adulterous relationship with a convicted paedophile (which she was told about at a young age and was made to keep it a secret from her father for years until it became public knowledge). Her mother is still openly dating that paedophile now.
She also has a younger brother (31M) who, as far as we know, was never a victim of the abuse himself, and doesn't know about it. He is still close to their mother.
Around 10 years ago, my wife finally cut off all contact with her mother. No one, apart from me, knows why she did that, but her brother has occasionally said things that imply he believes the reason is "because our mother is dating a paedophile". While this is of course a valid reason for cutting off your relationship with someone, it is barely 1% of the real issue. If she stopped dating the paedophile, it wouldn't fix any of the problems that caused the no-contact. The real problems are the things the mother herself did.
We got married 3 years ago and didn't invite my wife's mother. There was a minor fallout about this, where my wife's brother tried to convince us to invite her, but we didn't and it was all fine in the end.
This year, my wife's brother is getting married. When he sent out the invites, he told my wife that their mother would be there, but her paedophile boyfriend would not be invited (seemingly presuming that the boyfriend not being there would fix the no-contact issue). My wife said "I'm sorry, but I can't go if she's going to be there." He said "It's very important to me that you both are there." My wife didn't reply to that, as she'd already said what she meant.
A month or so later, my wife's brother contacted her to chase her RSVP for the wedding. She replied "I said before that I can't go if our mother is going. I was hoping I wouldn't have to spell out the reason, but I have a very good reason for not wanting to be in the same room as her. I was hoping you could take on trust that the reason is a good one. I would be happy to take you and [future spouse's name] out for a nice meal to celebrate your wedding, but I can't go to a wedding if our mother is there, I'm sorry."
We thought the subtext of this message was clear, i.e. there is a reason and it is the kind of thing people really don't want to talk about, the implication that that reason was probably CSA seemed natural. The brother didn't reply. We assumed this was because he accepted the reasoning, but was too awkward around that subject to actually say anything comforting or apologetic.
We were wrong. Today is one month until the wedding, and my wife received the following message from her brother:
"I hope you realise that not showing up for my wedding is something you can't take back."
This was really surprising, because we'd assumed that his radio silence over the last two months was born of awkwardness. If he wanted to guilt my wife into going, why wait until now? And why write a message that's so menacing, and seemingly leaves no way for her to say "OK, actually I will come" (which is presumably what he wants to happen). It has the energy of a drunk emotional text, but was sent at 9am, and he isn't the sort of person to drunk text.
My wife eventually replied giving more detail about the abuse she suffered, and crucially characterising it as abuse. She explained that she hadn't wanted to go into details, but she saw there was no choice. He has not replied to that message.
I've found this whole situation really odd, because, swapping it around, if my wife's brother had contacted her before our wedding and said "I can't go if our father is going to be there, I'm sorry, I have a good reason and hope you can trust that it is a good one", our first thought would've been "Oh no, poor [brother's name]", and our second would've been to try to find a way to uninvite the father, so that the victim would not be denied access to an event because of their abuser's attendance. The absolute worst case plausible scenario would have been not being able to uninvite the father, and being really apologetic to the brother about that fact, and totally accepting the reasonableness of his non-attendance.
There is no circumstance under which we would've tried to guilt him into coming by being weirdly threatening and totally refusing to engage with the actual issue at hand.
His behaviour seems utterly inexplicable, and it's left us wondering if there is some subtext to his or our messages that we are not understanding. Any advice, commiseration, or similar experiences would be greatly appreciated, thank you 🙏
