It's so normal! I hated my mums boyfriend so much. So, so much.
I couldn't put into words how much I hated him. They are no longer together. Talk to your mum, I am sure she will understand and you can negotiate some things.
You also want to have a "date night" with your mum so you n her go out and do fun things. This will make sure you maintain a happy relationship.
Yes its normal you feel like he is trying to take your dad's place. I hate my mum's partner but just stay out of it if she is happy then thats the main thing for me. If I was you i'd have a word with your mum don't tell her you hate him but explain you don't like his behaviour at times towards you and could he stop.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
