I got quite close to a mum of a son’s friend who goes to weekend martial arts school. This martial arts school is opposite a leisure centre. At first all good but then after a few months my son would come out upset by one of her children. It was always minor stuff and the staff didn’t say anything so I shrugged it off - we are not the Molly coddling type of parents. A few more months went by and in the summer holidays she insisted on taking my son and a few others to the holiday camp and taking them for lunch / dinner after. We tried to decline but it wasn’t an option. Myself and a few other mums met up for coffees in the leisure centre often and became closer.
Long story short I found out more about this other boys behaviour and I think he is quite manipulative. We then arranged a meal with the kids October half term but not with the original mum. She found out and went mental. We apologised but said we are adults and allowed to arrange things as we wish. She then blocked one of the other mums who was a bit more vocal however was ok with others - still friendly with all the boys.
Anyway all the boys still do the club and me and other mums share pick up / drop off and coordinate. The original mum is overly friendly with me, I want to keep a distance as she sent me a random ranting message on New Year’s Eve saying she’s upset that she’s never had an offer back for anything she’s done. I tried to make it clear in my reply that we don’t need her to help and no bad feeling but she doesn’t get the message and is still offering to help pick up my son in the mornings before club, my son is fine to do the activity with hers but says he can get a bit angry/ mean / funny sometimes. A few others have now left as they were older. It’s like trying to get through to someone but getting nowhere, but I will have to see her mid week and weekend weekly. Help!
