I hope things improve for you soon, OP. 🤞 I'm sure by Halfterm you'll be feeling a lot more included!
My children are young adults now, but generally I found the school gates a pretty friendly place. Something I've been hurt by though, is throughout the years of school gate chats, sharing lifts to kids' parties, catching up over coffee while they played etc, I felt actual friendships were formed. However, once the children moved on to secondary school it's as if those years hadn't happened!
Two mums who I felt particularly close to, seemed to cut me off once the children went to different secondary schools. I messaged them about meeting up, and was met with such vague replies, or no replies at all, I had to give up in the end. 🙁
I wondered if they'd been 'using' me all those years, one in particular used to regularly ask me for school-run help when working late, after-school childcare etc. I helped when I could, I considered her a friend. For her to cut me off so brutally, really hurt. I have plenty of acquaintances from the 'school gate' years, and we still stop and chat in town regularly. 🙂 These two though, I feel they only befriended me so they had someone to help them out, and that hurts. The School Gate can be a strange place at times!
