I don't like my dad's attitude

Extremely domineering. Insisting on looking over every contract I would sign. Recently struggling to look for a room in the town due to the serious housing crisis and lucky enough to be offered a room by a friend of a friend staying in a house, which I viewed thoroughly and with whom I chatted for an extended time. I did all the background check and received guarantee from my friend about her character.

Theoretically, I could have already signed a contract and moved in, but because of my dad's manner, things are still getting stuck as she is still preparing a contract that could satisfy him.

I am a 26-year old adult and my dad doesn't even live in the UK. He believes in random YouTubers more than his son who has lived here for years. I hate being denied agency and the idea that someone not even living here has the exclusive power to decide how I should live my life.

You are an adult -- ignore him.

I really hate what's happening

If your dad doesn't even live in the UK, how is he getting sight of the contracts; you have to be sending them to him, so stop doing that? However, if he is funding the accommodation then he's entitled to see what his money is being spent on.

My mum can simply pay for it since the rent is not too expensive, but he is kind of control freak and that's why it happens
