I’m sorry this happened to you. I also homeschool my kids and let me tell you, the cattiness and clique-ish behaviour amongst mothers I know within our co-op is crazy ridiculous! Its the reason I left mine and found other outlets for my kids to socialise. I lost them as friends too albeit not in such a extreme circumstance as yours. I don’t think this exclusive to homeschoolers, I just have a theory this kind of clique-ish behaviour is bound to happen in such groups unfortunately.

I think for me right now, I’ve focused on being my own best friend. It helps a lot. Maybe after some time, reach out the women who were on the peripheral of the group and perhaps this might strike up a friendship.
