Am I being disrespectful?

I am currently living with my mom and we are doing weekly pregnancy pictures using a board my sister made. My mom asked if I wanted to put the baby’s name on this week’s and I said no because we aren’t 100% sure if that’s what we are going with. She said she was 100% sure on the name and I told her again that we weren’t. She told me I needed to let my BF have the name he likes and not take that away from him. I told her that he isn’t 100% sure either. She again said she was 100% and loved the name. So I told her to have a baby and she could use it. She then stormed off and said I was being rude and disrespectful.

Then tonight I was watching a movie and she came and put something on the tv she wanted to show me. It was a song she wants my sister and I to learn and sing on camera for her birthday instead of a gift. I said I would rather do a gift. She asked me to look up what the song was so I did and told her title and artist. She asked me to look up the lyrics so I did and went to hand her the phone. She said she couldn’t read it cause she didn’t have her glasses. I said I didn’t feel like reading the whole song to her since I was cooking dinner and watching a movie.

She then came downstairs and told me that I am being rude and always blowing her off when she is just trying to connect with me. She said she doesn’t want me to talk to her all week. Just bring home my rent money and we can be done. Was I disrespectful or was she blowing it out or proportion?
