I don't even know if I can do anything tbh.
My mother told me she was leaving everything to my sister in her will because my sister is not married. My sister is a lot more successful than me both in terms of assets and job, he paid for her to study and bought her properties etc.
I'm really angry and hurt. My sister has been the favourite all my life but I never imagine my mum would take it this far.
I can't bring myself to speak to my mum, it's not about money it's about not acknowledging me or my dc in her will and the consequences to me in doing that.
The money would be life changing to me but pocket money to my sister, and aside from that who knows where either of us will be when she does die as it's not imminent.
Since then I've had other family members say I'm awful not speaking to my mum etc but I haven't mentioned why. I don't know if I'm being nasty and simply not respecting my mums decision to leave everything to a dc that apparently brought her more joy than me. No one else knows my mum has done this.
