My parents divorced when I was 10. My brother was 12.
My mother moved out, taking me with her, and my father kept my brother.
I never saw my father again, he didn't ever visit or want me to visit, never sent so much as a birthday card.
My mother made effort to see my brother.
Now I'm 40 and my brother is 42. We don't really talk; we're like strangers. He has a relationship with our dad, and a relationship with our mum.
I see mum occasionally, she was abusive so we have low contact.
She has much more to do with my brother - she wasn't abusive to him. I know my brother has benefitted financially from them both and has support from them - I have nothing.
It just feels shit today. Most days I just get on with life, but today it really hurts.
