AIBU to stop confiding in MIL after she shares personal details?

[RainbowStars27]

I don’t know if I’m overreacting but …
I genuinely get on very well with my MIL and we are close. She comes over and we chat or go for coffee etc.

However recently I have noticed that she has been sharing lots of thing I tell her (even personal things like our finances, health, my friendship issues etc) with other members in her (DP’s) family. This is even after I have said ‘oh please keep that to yourself!’

Nothing I have said is top secret and I don’t particularly mind, but it just annoys me that the whole family now knows me and DPs business when I have explicitly asked she doesn’t share.

DP has just said she has form for being a gossip. It just makes me not want to tell her anything personal now!! I know she hasn’t shared anything awful but it still upsets me.

Am I overreacting?

I had the opposite upbringing - things were not to be discussed outside the immediate family, and frankly that’s what I prefer. I know what the son of one of PIL’s friends received as a VR payment. PIL will not know what I’m getting. They did not know when we paid our mortgage off, not how much our holidays cost. They knew practically nothing when I had some kidney trouble a few months ago. They’ve never said anything, but I have made it clear to DH that if he tells them anything about my health issues then I will stop telling him anything in the future.

Our eldest DS was kept in hospital overnight years ago as he fell off his bike and partly landed on a tree stump. The hospital wanted to scan his stomach area as a precaution but the unit was closed when we got there so they advised keeping him in for an early morning scan. He was fine - the calls from MIL were more stressful than the actual situation.

Never mind your MIL, it's reasonable to be a bit close mouthed with anyone who chats your stuff. Over my long life, I've had no end of people asking if I'd heard about (eg) what happened to Sam, and then regale me with the details, finishing with 'He told me not to tell anyone, but I know you won't pass it on.'

I’m surprised you confided in her if she is a renowned gossip!

Strict information diet going forward.

My own mum is like this. She just over shares. As a result she knows only what I’m prepared for all my aunts and half my cousins to know too. We are still quite close, it’s fine.
