<human>: My girlfriend and i have been together for 6 months, and have gotten along very well. I'm in love with her, and i think she's fantastic. However, we get in fights about really stupid stuff. Here is an example:

I was talking to her about the flute (we were both in band back in the high school that we went to) and she mentioned how weird it was that this year her band show has 4 parts. I mention that it was probably because the old band director from the year before tried to limit the amount of parts because of the size of the band. She disagrees.

We immediately start fighting, she's saying i have no idea what I'm talking about, i say that I'm in a more advanced program and have more experience, etc...  

After that i say i want to stop fighting. She says ok, but then for the next 30 minutes, she gives me super passive aggressive replies to all my questions. i asker where she wants to go, she says she doesn't care. i ask if she wants to smoke, she says she doesn't care. other than that, silence.

The main problem that I have is that if i want to talk about it, she'll say that it won't help and that she just has to get over it, yet after that, she still gives me passive aggressive responses.

The other problem is that most of the things we fight about a super insignificant, like whether or not her home town has senior pictures, or ice cream, but both of us are too stubborn to say the other person is right.

I love this girl, and i want this relationship to work. What should i do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My girlfriend and i fight often, usually about insignificant stuff, and i feel like she's super passive aggressive in the way she fights.
