I'm mad at my roommate because she is uppity in my opinion.
What do you want from her?
She should be nicer to me.
You should stand up for yourself if you think someone is being rude to you. Let her know that is not okay to treat you that way.
I should do something. I probably shouldn't say anything to her though and I will end up losing this fight.
You need to stand up and set boundaries. People deserve to respected especially if you live together. If you can't work through it you may need to find a new person to assume the lease.
