Definitely report this to the head teacher. If you have her email address I’d wrote an initial mail now as she’ll be working at some points, and could do with a heads up before the start of term.
I wouldn’t write the actual issue though as you need to be able to talk this through thoroughly with the ht before she gets the other teachers voice in her head and it all gets minimised and laughed off...
The way two phrases it sums up why it’s making me so uncomfortable...
“she (bizarrely) is, at best, unprofessional enough to have closed the circle by mentioning it to your DS. ”
- How is she in possession of this information?
And what does this mean about your abusive ex and how long he’s kept tabs on you unbeknownst to you... the risk factors go up losds here potentially and I can’t see any ‘ha ha ha conicsbtence’ type of story covering it, it’s too bizarre.
- Why on earth does she feel it’s in her remit to ‘close the circle’ by giving your son personal (and odd in this context) information about his mummy on his first time at school??? It’s naive st best... but this naivity could shows that she is dancing to a different drummer than ‘professionalism first’ and it may well be the controlling boyfriend comes first, and who cares about appropriate boundaries at work...
I’d be asking why she thinks it’s ok to creates intimate/ over familiar connections in DS’s mind, when she should be distancing herself and being nothing but professionalism at its best to the son of her boyfriends ex partner?
Even if she doesn’t know her partner was abusive and you fled in fear of your life... why doesn’t she? Is she more easily controlled by him? Or deep in the fog and not admitting any issues in her relationship? Or maybe she’s cut from his cloth. Who knows? But I wouldn’t be imagining it’s all rainbows and cotton candy, although I wouldn’t immediately paint her as a fellow victim either. What I think she might be is someone in a messy relationship with no perspective and if she’s not able to keep her professional/personal boundaries up under pressure from her partner, then she shouldn’t be anywhere near my child.
I would give her one warning shot across the bows first though, supported by the ht, making it clear what is expected and also being clear what the consequences are of breaking any professional boundaries... and if there’s any hint of her behaving weirdly again I’d be leaving.
I know it’s horribly disruptive, but if your ds has potentially two years with her, you can’t be worrying about her every day.
I’d ask your address to be kept completely confidential and away from her and other staff though, in case she goes home and whines to the partner and it escalates. And remove your contact details from any other public platforms...
