<human>: Well, essentially, my girlfriend nags and tells me what to do fairly frequently. For the most part, we have a stable relationship but one thing that has really been making me lose my attraction for her recently is the way she nags me constantly about silly and trivial things. 

For example, I run a weekly information seminar at my University for other students that attend my University, it usually gets around 20-25 people to attend. This week, my girlfriend didn't seem to like how I arranged chairs in our meeting room and suggested a couple times that I change them. I told her why I didn't think that was a good idea and continued doing my own thing. When other people began to enter the room, she started asking them if they thought the current set up of chairs was stupid. They told her that no they didn't, but that didn't stop her from saying it over and over. I talked to her about this and told her that I really didn't like it when she pushes doing things her way into many aspects of my life, such as this occasion, backseat driving, and telling my little brothers to do things a certain way when she visits my family with me but she says that shes just trying to help me out.

Am I just being selfish and hardheaded and not letting her help me and listening to viewpoints that aren't mine? Or is my girlfriend a genuine nag?

Give me the gist of the text in a nutshell
<bot>: My girlfriend nags me, but says that shes just trying to help me out, but it drives me crazy. Am I being stubborn, or is she actually a nag?
