Is she just using me?

all of my friends say that my girlfriend is using me and so do my parents they all say im blinded by love although I spend a lot of my paycheck on her she doesnt ask me 2 but sometimes I think she expects it also before I met her she was sexually abused which unfortunately means sex is pretty much out of the question but we are very close when we make love I sometimes feel like its a one way thing so often I dont even want 2

well what is she asking you to buy her and does she have a job? and some time you have to say no I need to buy stuff for my self and if she realy need money help her find a job
