Okay so about a week ago my girlfriend last here phone, It was a nice phone camera, internet, whole nine right. Anyway we happen to have the same phone so she starts telling me about it and how she lost it and I say "well why dont you go get the same phone from the place that we got it?" she tells me that since the phone was so expensive the T mobile wont replace it for free. So I ask her why doesnt she just go and get another phone, one thats maybe not as nice and she starts complaining about how my phone would then be nicer then hers... so I say well then maybe we can trade phones or something and ill go pick out another phone for myself and she says okay. So today she had to borrow my phone for class and without telling me she goes out and gets our phones changed. Calls me on her phone, which happens to be my old phone and tells me she changed them. Now I kind of got upset because I wanted to pick out my own phone and see what deals I could get (she cant haggle for shit). She tells me to get over it or something like that and says she cant believe the shit I was pulling etc...


Now what do you think about this whole problem should I just pony up and let it go, or do I have a right to be upset about it and her treating me badly?
