My dad has for some years been a believer of many, many conspiracy theories. Flat earth, no moon landing, lizard people, loves David Icke, is anti-vax etc etc.
His latest obsession is that covid is fake. He relentlessly posts YouTube videos on Facebook to "prove" his point. I haven't really replied to any of them apart from once (very politely) and then gave up as no one can get through to him. He's even posted openly racist stuff and complaining about black lives matter and dismissing their concerns entirely because he "doesn't see racism where he lives or on the news" so therefore he seems to think it doesn't exist. But I digress...
He's only been to visit us once since lockdown and despite me asking him to bring a chair so he could sit in the garden with us, he didn't bring one so he stood at our gate and we chatted for a bit. He seemed ok but didn't stay long despite dd1 and dd2 having not seen him for ages.
I've had very little contact from him over the last few months and when I've messaged him to see if he wants to come and see us he keeps making excuses not to come. This makes me really sad as dd1 and dd2 are missing everyone and it hurts that he won't make the effort to come and see them.
When I messaged him to ask if he wanted to come round the other day he said "are you still doing the 2 meter anti social thing?" I explained that yes, we were because we have vulnerable family members and a friend who has just undergone chemotherapy and radiotherapy. He got annoyed and suggested that I was putting friends before family. He even suggested that our friend, who has just spent 2 months having cancer treatment and being unable to leave the house, should isolate himself! This shocked and upset me a lot. I politely explained why we would never ask him to do that. I also explained that we are social distancing with everyone apart from my mum and my partners mum because they are in our bubble. He didn't reply to me.
The next day I suggested he came for a walk with us, which he agreed to but because it rained in the morning and we moved it after lunch he said it was too long a journey to come for a short time. He lives about 45 mins away so it's kind of believable but I still feel like he just can't be bothered or doesn't want to come.
He is normally not a confrontational person at all and would do anything to avoid an argument but lately, via Facebook, he's been really nasty to his sister and rude my mum (they have been separated most of my life but normally get on well) and has been very insulting to many people.
It's worth noting that he is type one diabetic and may or may not be using his insulin properly. I also worry about early onset dementia as my grandad had dementia, albeit not until his late 80's. I don't know my dads partner well enough to speak to her about him and my younger brother lives on the other side of the country so he's not seen him either.
I don't really know where to go from here but I'm so worried I'm going to end up losing contact with him completely and my girls won't have a grandad.
