Apologies for the very long post, but I feel full explanation is relevant.
As background. My dad left the family home when I was 10 for my step mum. This was 40 years ago. Before he left, he introduced her to us as a work colleague, whilst I later realised were having an affair. He left my mum & I fully admit I took my mum's side, but for lots of reasons, even if I'd met her independently she was never going to be someone I would have liked (I'm aware this sounds judgemental).
During my teenage years our contact was once a week on a Friday night. Obviously as I got older Friday nights became my social nights, so direct contact dwindled.
As I left home, went to uni, lived in various parts of the country our contact became less & quite superficial. When I got married his condition of attending was that she was there as well. I went along with it all to placate everyone.
I moved back to my home town & contact became a bit more frequent. My mum died (the only time he stepped up as support for me)
My younger brother has Down's syndrome and lives in a care home. My dad's attitude on this has always been "he's happy there, I don't need to bother". Since my mum died, I've been his primary carer. I have no problem with this, he's my brother & I love him.
I have 3 children. My youngest has learning disabilities & severe autism. My dad said "put him in a home" that was really his attitude
Anyway contact has become lower & lower. I send birthday, Christmas cards etc. Absolutely nothing in return for at least 3 years. He's asked me why I don't visit & Ive been honest that I find it hard to bother when he's missed a lot of significant birthdays, not me but his grandchildren, 18th, 21st etc.
But in the last 6 months he's become ill, partly old age, some physical problems that have resulted in him being hospitalised, also increasing and obvious dementia. I admit that due to my low contact I hadn't been aware of some of this till after the event.
Over the last couple of weeks there's been a couple of phone calls, some explanation on both sides & an agreement that I'll phone him regularly each week at 6pm on a Sunday. Also I'll go and see him on his birthday in a couple of weeks.
Today I get a phone call from my step-mum. It started off with a "you need to see your dad" "he's so upset you don't see him, he's old & won't have long left". Within a minute the tone changed she started with "you're bloody disgusting, you're a disgrace" & ended with her slamming the phone down without me getting a word in.
To get to the point (thanks for staying with me till now!) I'm absolutely conflicted. I'm so angry at being spoken to like that. I know I'm not the best daughter, but he's a shit father. I hate her. He's always chosen her above us. He's made his choice. He's put all responsibility for my brother on to me. He has expressed abhorrent attitudes about the care of my brother and my disabled child.
But above all I'm still that 10 year old that loved her dad unconditionally & was left hurt & rejected. It feels like it's all come to a head & I just don't know where to go with it.
