Ok this is a long story but I really need some opinions..

After the death of my brother, the family split into 2 groups. 1 - my mum and I, 2 - my 2 sisters and their children (children between ages of 13-28 then).

My sister A and B never really had a good relationship with my mum as she divorced their dad and married mine and then had me. It must have been a very hard time for them and they clearly had a different upbringing than I did. My brother had a good relationship with everyone for some reason it didn’t affect him so much or perhaps he was the peace maker. Anyway, my mum and dad moved to a different country and my sisters didn’t see them as much rather once or twice a year. Then when my brother died my sister A said some terrible things to my mum. She was obviously grieving but on the day after he died mum was sobbing at losing her son and she just started screaming everything at her and after ages screaming that she wishes she was dead. It was abusive and wrong. Mum was broken on the floor and I stopped my sister and picked my mum up and took her outside to the car (we were at my sisters house as my brother died in the UK close to where she is living and no one else lives there), picked up her and my bags and drove us until I could find a hotel.

The next few days my sister B was driving to where sister A lives and sister A spoke to the priest. I arranged the death certificate, cleaned out my brothers apartment, talked with the funeral home etc. on the day of the funeral no one from the family spoke to me or my mum we just stood there. I know they lost their brother but so had I and my mum had lost her son. After the funeral we flew back home.

Sister A then started calling and texting mum and I when she got drunk being abusive and destructive. So mum and I both told her if she speaks to us like that we didnt want to speak to her.

This was in January 2013. Since then I’ve not spoken to anyone in my family. Not my 2 sisters. Not their children.

Do you think I should ever speak to any of them? Have you ever had an estranged relationship? Did you ever talk again? Is it broken forever? Can I speak to my one sister without allowing my other sister into mine and my mums life again. I am happier and better without the abuse she brings to my life. What do you think?
