Thank you for all the insightful posts lots of food for thought
. I guess IAB a bit u in thinking once unpopular always unpopular.
I agree that some people have an aura which maybe due to "naturally playing out some very subtle social cues. " as Silver suggested.
I suppose it is also about fitting in.
I have always thought that if you happen to have the right 'assets' that are desirable in a social setting people will accept you more easily. For example, in a job environment or at Uni and even doing sports or music, if you a are good at the what you are doing you will be sought out and get included.
I have experienced this at various times but the problem is that I although. I like socialising I am exhausted quickly (probably introvert) and question myself and how I might have been perceived afterwards. So when people approach me I withdraw slightly and when people ignore me I get anxious and feel sidelined.

Maybe I just haven't the necessary social skills.
This has started bothering me mostly because I worry that ds will be left out at school. I am certainly not part of the the 'inner circle' of mums at school. Because of this ds doesn't get invited to many playdates or parties.
When ds started primary school one of the mums viscously gossiping about me. I have no idea why as I had not previously spoken to her much but she seems to hate me for some reason. Unfortunately for me she knows absolutely everyone around here and people who had never met me before turn away from me when I attempt to chat to them at the children's birthday parties or at the school playground.
That has made me incredibly anxious and eager to please but I mostly feel like an idiot in the school setting.
But that is not really the problem I think it is something to do with me fundamentally. Even though I believe i am genuinely nice and try to be there for friends in need, help out when needed and don't gossip in a negative way about others, I feel barely tolerated. Maybe it's because I am insecure and people pick up on this. Also since having kids, i have less patience as I am tired and exhausted most of the time.
I can't see myself changing much so probably have to accept this..... or?
Hopefully it won't affect the dc's social potential.
