Should I back away from potential friendship

[Toni0987654321]

I've met a mum at school in the playground through our children been friends, we've met up a couple of times for coffee and have been texting and slowly starting a friendship outside of the playground.
I told this mum something personal about myself and she's told another mum in the playground. I know because the one she told approached me saying ohh I can't believe you are concidring moving jobs! I was really taken back as I haven't told anyone else! And certainly not my current employer.
Now I'm left wondering if I should completely back away as I cant trust this person or if I'm massively over reacting! I just think my personal details aren't for her to share regardless how insignificant they seem,and seems no reason to share it other then plain gossiping.
Now I feel I'm back in the playground haha and acting like a teenager but it's really irritated me.
Would you back away and leave her to it?
Sorry for the rant 😅

If you’ve only met up a couple of times why would you think you could trust her anyway? Thing is it sounds like what she repeated was to her just general chit chat anyway. I mean did you tell her not to discuss it with anyone else or that it was sensitive? Ultimately if there are things you just don’t want others knowing then just don’t tell anyone. There’s a saying that if you tell one person you might as well tell everyone.

Well it's not private and personal though, is it? Because YOU shared it with a relative stranger! If you'd wanted it kept quiet, you should have said, otherwise yes of course it's gossip, cos if you're not talking about yourself, you have to talk about the other mums!

It's not gossip though? It's a completely uninteresting piece of information. It's not like telling someone @toni987 is having an affair with the milkman and gets free pints or something.

I can totally imagine her telling someone she's been for coffee or whatever with you and the other person saying,' Oh what does she do?' And being told 'She's lollipop lady but she's looking for another job'. It's small talk and of no real interest to anyone.

Did you tell her it was a secret!!?

Free pints? She’s cheap. I’d be wanting at least half a dozen eggs and a carton of Umbongo too!

It's such a benign piece of information, she probably didn't even consider it gossip. It can easily come up in conversation, eg "I'm moving jobs", "You as well? I was just talking to Toni and she's switching jobs as well".
Or "How is Toni, haven't spoken to her in ages" "She's fine, busy job hunting"
That sort of thing.
