Hi
@Tuesday Wilson I looked after my dad for a couple of years full time and had to give up work so I suffered financially, no wages, just carers allowance. It's not fair but I managed. I eventually had to move in with him 24/7 and to be honest carers allowance is a joke for 24/7 care. For that final year dad paid for all of the shopping including my share of the food etc. He also treated me a few times but he could afford it. He paid for all the petrol in his car which I used for his benefit and also mine on the rare occasions that I went home. I have my own home but my husband had to look after that and pay the bills because I couldn't as I had no income other than carers allowance.
I certainly don't consider that I profited from any of this. In fact I lost 3 years wages and when dad died I found myself at the age of 63 with no chance of employment (covid didn't help) and no chance of any benefits so I am living on my savings until I reach pension age in 2022
As long as your dad can afford it then I don't see any problem with him helping you out. What would he pay for a care home. The big problem that I would worry about is, will anybody help you out to give you a break, do you have siblings who can give you the odd weekend off because it will get harder as you go along.
It's a lot to think about and it could leave you financially much worse off after a time but your dad saves care fees so only you can weigh it up.
