Thanks everyone, sincerely, thank you. It's easy to feel like I'm going mad or being unreasonable. I very grateful to you all. x
Pay attention to this. You know in your heart you're a reasonable person. So when you're in a relationship and you feel like this, it's not you that's the problem, it's the relationship.
At best he's planning to use you as a cash cow and possibly lining up a carer he won't have to pay for, because a paid carer would impact on his son's inheritance.
At worst he's totally controlling and wants you paying rent so
a) you have no security, no home of your own and can't save for one so
b) you can't easily leave making it easier for him to control you with threats (you don't like it you know where the door is, either openly said or implied). He'd already be controlling you by default because
c) working part time and paying rent, also paying unnecessarily high bills (for you, compared to bills on your planned smaller purchased home) on a big house, you'll not only have more time to spend with him you'll also have
d) no money to go out with and therefore
e) limited capacity to make friends, in this new location he's isolated you in where you know nobody.
As they say, more red flags than a communist rally. This is not a healthy relationship.
After only one year you don't really know him. After a lengthy dodgy relationship you don't know right from wrong (understandable).
