BIL Text Me In Error-he is having an affair?

230 replies

Robertsmithsnan · 24/02/2026 06:48

I sent my BIL a message last week, my name starts with R.
Received a message at 7am, “R, you are the light of my life, I love you with all my heart”
He sent this to me by mistake.
The “R” person is someone he works with. What do I do?

Is he your BIL as in your sisters husband, or your husband’s brother?

HighStreetOtter · 24/02/2026 06:50

Is he your sisters husband, or your husbands brother?

Velvian · 24/02/2026 06:51

Has he realised? If so, what was his explanation?
Do you and the other R have the same 1st name?

I think i would need a bit more before jumping to that conclusion.

Whoever's brother/husband he is, he is definitely shitting himself right now.

kotordreams · 24/02/2026 06:52

Your BIL as in married to your sister or your husband’s brother? Husbands brother - ask your husband his thoughts and leave it to him. Your sister’s husband have a chat with her and sound out if everything is ok.

Is he your sister's husband or your DH's brother?

Silverbirchleaf · 24/02/2026 06:53

Doesn’t look good.

I’d be tempted to reply saying that you think he’d sent to the wrong person, and maybe even questioning why he’s declaring his love for someone else. If he is having an affair, or even emotional affair, it will get him panicking.

would I show it to his wife? Not sure. Maybe I’d give him a chance to explain things first.

tartyflette · 24/02/2026 06:53

Sorry, OP, when i first went to answer no-one else had replied yet.

itsmeits · 24/02/2026 06:54

Screenshot it before he tells you it wasn't real or a dream!

Zoraflora · 24/02/2026 06:54

I wouldnt do anything for the moment…. wait and see if he realises his mistake and sends a follow up message.
Can you do a bit of discreet snooping to see if he is having an affair with “R” from work.

firstofallimadelight · 24/02/2026 06:57

If it’s your dhs brother I’d tell your dh and leave him to manage it or discuss together what to do next.

if it’s your sisters husband I’d tell your sister and support her while she decides what to do with the information.

I'd just text back saying " I think you need a conversation with your wife. Immediately "

exhaustDAD · 24/02/2026 07:00

I don't think it would matter to me which way he became my BIL. I'd screenshot it to make sure the message is saved, and give him a chance to a) have a reasonable explanation (willing to bet he wouldn't), or b) go to his wife to talk before I do.

This 👆 Add “before I do” to the end

This is probably what I would do.
You can't leave it though. He had unfairly involved you, so tell him you are giving him the opportunity to tell her before you do. If you ask for an explanation he'll minimise.

Fontet · 24/02/2026 07:08

If the show was on the other foot…would you want to be told? How would you feel if you eventually found out knowing a member of your family already knew but kept it quiet…difficult situation but go with your heart x

UpDownAllAround1 · 24/02/2026 07:09

How do you know it is someone he works with?

Thesnailonthewhale · 24/02/2026 07:12

Maybe it's for you...

Paraguay · 24/02/2026 07:12

Oooh

Tumbler2121 · 24/02/2026 07:14

It could also be a joke message between colleagues if that’s the exact wording.

MushMonster · 24/02/2026 07:15

But do you know how your name is saved on his phone?
Because if he is your sister's husband, and let's say her name is Amy, you could be under Amy's sister and he meant to send it to your sister, just only read the first word.
If he is your husband's brother.... show it to your husband.

MushMonster · 24/02/2026 07:18

Sorry, just realised the name is in the text itself!

Imagine he might use this as his daft excuse

It wasn’t the sister’s name in the message though?!

I thought the same.
