Caught Brother's wife cheating and don't know what to do next, Brother is missing atm!

Hi reddit,

It is with utter disappointment i come here to ask this question i feel extremely embarassed to ask this but the time has come for this, I really do not have any experience as to how to handle this situation and im completely in awe as to what to do

My brother who got married in 2019 has a good life abroad is busting his ass out in the middle east to earn money for his family of 4 has been cheated on, i really do not know how to get this off my chest. He's been a complete mess and he's been out of contact since a week or so with no real updates.

A bit of a background

My brother is a really naive person, tbh he has this habit of helping people every now and then and has been in trouble cause of this but still he doesn't let go of this, he's not really that well educated in terms of degrees but he does have a lot of experience with middle eastern businesses he is a sales and marketing manager at a saudi arabian firm earns good money he lost his job in 2023 then he came back home to be with his wife stayed here for 2 years and then left in March 2026 , During those 2 years he came home he tried to be there for his wife supported her and stayed together which she wanted as well they had occasional fights but nothing to that degree . He even had his second child in 2025 and was really happy with it and family was doing really well but he did inform us during this whole period from 2020-2025 that his wife doesn't really appreciate what he does and is a bit absent in terms of the relationship she doesn't seem to have any interest but we thought it might be a woman thing after giving birth so we let it go and forced him to stay with her so he had no choice but he did so !

RECENTLY SHE'S been abusing her children not feeding them properly and beating the f out of them when they don't behave we tried stopping it but all went in vain!!

A week ago i was visiting his house to bring some gifts for the children i have the keys to his house i went in there was no one around the house i thought "hmm,weird" but then from the main bedroom i heard her talking to someone and laughing real loud and making some sort of sounds " i Thought "maybe isnt the best time to visit " i shrugged and kept the gifts by the cupboard was about to leave but then i heard someone on the speaker phone it was some man and it defintely wasnt my brother i moved closer and just stayed put by the door.

it was really unusual i have never seen her so enthusiastic talking to someone she's a bit of an introvert and never really expressed herself to someone i just kept myself hidden by the door and heard the conversation.

It was something related to sexting and i could hear the other man from her speaker " IT WASN'T MY BROTHER"

I was the one who caught her unfortunately sucks to be me i had this weird stomach turning feeling by their chats couldnt stay there for more than 2 minutes or so i got up and left the house

The next day i called my other brother to keep an eye on her and see as to what shes upto he said he'll look into it and then while she went to take a bath he got his hands on her phone and tried to unlock it via the pattern that was etched into the glass with the constant fingerprints she had. And with no surprise she had sexted multiple men 3 to be exact 2 from the same city we live in and one from the nearby county

SHE WAS SEXTING all of the 3 men at the same time there were obscene pics and in one of the chats she also sent a pic of the baby who's hardly a year old now to some man she hardly knows

SHE'S been meeting up with these men in hotels,rooms god knows what

to my utter disbelief all of this has been caught we have recorded the chats from her whatsapp as well

The thing is my brother wants a divorce now and he's not even sure as to the kids are his or not and he's been a complete mess

I never had something like this come up before in my life so cannot even comprehend as to how to solve this, its going to be long tedious and not to mention the law will side by the woman but still i want my brother to be happy, I cannot help myself

My brother has gone missing i tried his cell his iphone location is still 8 days old

His friends do not know as to where he is my brother hasn't met them for weeks they mentioned he looked tired when they met about 2 weeks back and lets say he didnt really look in the best

EDIT: I already sent the evidence to him but he didn't see it the message still has a single tick, his mom however says that they should file for a divorce
