Looking for advice on relating to a friend who has become more and more toxically negative about me and my children over the last few years. Little comments questioning my parenting, the character of my (kind) children, my career... I don't spend any one to one time with her but she's in a group of friends who meet up regularly, we have all been friends since our children were in a parent and baby care group. I am a chatty person and find it hard not responding when spoken to. How do I shut down conversation and particularly the probing questions that I know from experience are going to lead to me being upset? It's ok (ish) in a group but she tends to pick me out at some point and then the questions and comments start. I know it may sound a bit pathetic but it's getting me down.
