<human>: Mind you this is after having planned a surprise night on the town with all her friends for her birthday and her having a blast and telling me so herself. So this morning we wake and I fumble to let out our dog, and because of the fumbling she says I just realized you are the reason I am in a bad mood all the time. I've gotten that line in variation four more times this morning. I went back to bed because I was feeling low and didn't want to set her off anymore. She came in and we rough housed with dog on the bed, and by accident she hit her nose on my head. She storms out the room, says I ruin her life and slams the door. Anytime she mad she lashes out at me, if I leave the faucet dripping, if I buy the wrong pizza rolls. For a while in our relationship I had a problem with lying about mundane things and that would really set off her anger, but I'm a couple of months past that and I have been on perfect behavior and still get reprimanded. After 3 years I don't know how much more I can stand, I love her, but she brings in all this negativity and hostility and blames it on me.

Can you condense the text into a few key points?
<bot>: My girlfriend blames all her unhappiness on me, even though I'm trying my hardest, and any human mistake is met with anger.
