My son is 17. He has a long time friend, they have drifted apart previously as my son lives away which has likely impacted the friendship, but they have been in touch more recently. It is felt my sons friend has changed, she is different to how she was before in terms of her personality.
I am close friends with friend's mum.
A mutual friend of my son and his friend has informed my son that other friend is having a Halloween party. My son messaged, and asked if he could go. Friend told my son that she was at her limit on numbers for the party and her mum wouldn't budge on this (we knew this was BS as her mum would have loved my son there). Sons friend has told mutual friend that she thought of inviting my son, but her friendship group can be quite offensive and didnt want my son to feel uncomfortable and judged- these were her words. Now- my son is very proudly gay, and a ballet dancer. I have denoted it down to these characteristics that friend's friendship group would likely make reference to- what else would friend feel my son would feel judged/ (rephrase- insulted) about?
I have stood back while sons friend has distanced herself and actively put barriers up between her and my son, but to think so little of my son, who she has known since they were in reception, to exclude him rather than advocate for him/challenge her friendship group on what are likely harmful attitudes is so disappointing. To lie to him is so cowardly. Now even if he did get invited he wont be going. But I feel I cannot let this sit. I want to tell friend's mum- what would you do?
