My neice has not spoken to me for 7 years since she came to stay when she had no where else to go as she had fallen out with her mum, and treated me, my mum and our house appallingly, so I gave her a month to find somewhere else, so I understand and am not particularly bothered that I dont have an invite, however, she also has not invited my mum, who she has not spoken to for 4 years, even though my mum still phones her, leaves messages, but my niece never phones back. My neice doesnt tell people we weren't invited, she tells them we didnt want to go, or we are sulking over an argument from years ago, which is not true. My sister, even though she knows this is not true, just goes along with it as she says she is not getting involved and it shouldnt matter to us what my niece says as we live so far away from the extended family ( my sister moved to be near her husbands family, so we never got invited to anything family related). But it is extremely frustrating and very hurtful for my mum. I dont know how to make my mum feel better.
