My dd aged 16 had a falling out with her friend in March last year and they haven’t spoken since as far as I am aware. DD has since made friends with others and seems happy, ex friend has moved on too and gone to a different sixth form. In Kuly it was their prom and by mistake I texted ex friend thinking it was someone else inviting her over for a pre prom get together. Realising my mistake I then texted her again to say so sorry I’d make a mistake and texted the wrong person. No contact since. This morning I have received a long message saying I should never have sent the messsgr, the group was toxic etc. iMy husband thinks I should just message apologising again and just leave it at that. AIU in contacting the mum of the 16!year old friend to apologise and say what has happened? This has obviously distressed my daughters old friend and I don’t want to cross any lines. What would you do?
