So my Dd best friend is an absolute nightmare! She's constantly putting her down, being genuinely horrible most of the time for no reason! It's really getting my Dd down and so insecure it's horrible to watch... I've been holding my tongue for so long it's driving me mad! I'm good friends with the girls mother so it's highly awkward! But this girl is pushing all the wrong buttons 🤬 AIBU and should just leave them to it both 15 Yo or do I have a word and risk both friendships, when they get on they are like sisters but when the other girl is horrible it's unbearable?!__
