My dad died 6 years ago, the day after my ds was born, it was a horrible time, made worse by my narc mother
My partner left when ds was 4months old and as I became a single parent on benefits my mum lived in the family home and spent £50,000 on a new extension, has a considerable income and goes on cruises and other holidays every year.
Did she help me ? No, and only when I started to pick myself up, work, get another partner years later did she offer, knowing full well I would refuse as I didn't need it.
They are selfish people better out of your life, it hurts because you let them in, my brother gets mad about my mum spending my dads money because she emotionally abused him all her life, but I can't get cross because I know that's what's she's like and I don't expect ANYTHING from the selfish cow.
I guess all I can say is I sympathise and empathise with your situation
