Is it normal to dislike my mum so much?

I think so she got really jealous when I was going to apply to an estate agency job and she's jealous of how close I am with her dad. He pays everything that parents should pay, because mine don't. If he didn't buy my clothes I wouldn't have any- I think she hates that. But he pays her mortgage? I think my mum and your bf mum are insecure but it makes them quite nasty
