<human>: A little background I suffer from depression and not two months ago I got away from my emotionally abusive mother and step dad. Since then I've started to do things I want to do and not feel guilty about thinking about myself for a change I got support from my girlfriend and my father plus my elder sister which I'm grateful for and I now live with my father who my mother has not allowed me to contact since I was 14. 
I've been with my girlfriend for nearly a year who suffers from borderline personality disorder.

But of late I just feel emotionally, physically and mentally drained. I've been arguing with my girlfriend for nearly three days because of well everything nearly from our future to me not going to see her because I was cooking and eating dinner with my father who I live with. But it's not just that when we go out I have to pay for everything and if I don't she'll get in a mood with me.
Of late I decided to reward myself by wanting to build myself a new gaming pc (To those aware they aren't cheap I'm expecting to pay £1, 000 at most) for getting away from my mother. My girlfriend has proceeded to make me feel guilty about my decision by saying I could use the money on going out with her which yes I could but this is something I wanted to do for ages and I have just about saved up the money.

But with all the arguing of late I feel that I've upset her for wanting to do something for myself and that she feels the way she does and not only that but I've noticed her be more manipulative of late when it comes to my decisions.

I care for her I really do and we've both helped each other so much but it's at a point now where I don't know what to do anymore.

Can you give me a shortened version of the text?
