[Always *]

The whole "she's a small town kid and your a city kid" bit is insane. Like I understand where she might get the idea from. Lots of people from cities act like people from small towns must be ignorant red necks who know nothing but the town, but that goes 2 ways where city people are stuck up ignorant city slickers who never leave the city. It's a ridiculous stereotype, but it's possible people have said stuff that easily triggers her.

And as for the whole money thing, yes, I think she is being insecure, but it might help if you didn't mention prices. I am not saying it is wrong too. But yeah, it is possible that she was already insecure about her family situation and that having to move in with your family has exacerbated it. You should definitely talk to her and just try to get to the bottom of the matter. You should be allowed to be proud of your electronics and not have her shoving it in your face and acting like you're just trying to flaunt it.
