Am i wrong?

Is it bad to not like your mother in law? I just hate how she doesn't give me and my so space. And he's a grown ass man who doesn't need his mommy bossing him around! Like we can't even plan something, bc if she call him that he needs to do something for her we can't carry out with our plans! Idk am I wrong? I don't even like going with her to run Arron's bc she'll just be a nosy little bitch and she asks questions about my family that are personal! That no one else should know, but she finds a way to find out and nag me about it when it's none of her damn business! Anyone out there the same as me? Any suggestions? What should I do?
