Struggling with my past

Hi I’m posting on this sub because I’m struggling at the minute,what I’m struggling with is ..

Many years ago my dad was physically abusive to my mum.my father is dead now.

But what is hurting is that other family members made up their own reason why my mum fled from my father .one day I was at a family gathering and a close family member said she was abused she went on to say that I was nearly abused by this family member and that is why my mum left the city .This did not happen !I was that flabbergasted that I did not put her straight as to why we left our home town,

Not one person has put her straight that this isn’t why we left I saw my dad physically abuse my mum with my own eyes .and my mum left taking us kids

I don’t know why it’s hurting so much so I just want to vent it here.even my fathers ex partner who my father confided in won’t put everyone straight that my mum got abused and that’s why she left .

When my dad was in his last years of life suffering from cancer it turns out that his partner not my mum )had become an abuser I heard her try hit my dad he probably felt he deserved it but that’s another story.

I always thought his new partner was a narc anyway and kept my distance as she medalled and was a gossiper smoker and drank a lot compared to me.

But I just feel like shaking everyone and saying my mum did not leave because of that she left because of my father but the rest of the family are so tight I don’t think they would believe me even though I know it to be true.

I’m just venting my thoughts thanks for being here
