<human>: Can you give me the gist of the text in a nutshell?

It begins like this - it was our 6th anniversary and we had both agreed not to spend more than $150 on a gift.  Because of my job, sometimes i don't make great money if there is a dead season. I got her what every gamer girl likes - a gaming console. It was a ps3, with 5 games, for $75. 

On our anniversary, the gift exchange. She  bought me a $500 computer, knowing that our limit was $150. 

When we exchanged presents, she was joyed to have something to game on. Four hours later, while i was on a service call, i got a text saying that  she was leaving me and that my stuff was on the porch. 

When i got home, my stuff was indeed on the porch. I unlocked the door and wanted to see if this was just an elaborate ruse or something, thinking that she had something else planned... But i was wrong. She immediately started screaming at me to get out, that I was cheap and she didn't want to see me again. That she hated me, and that I was going to be arrested if I didn't leave. I'm still totally flabbergasted about this, I have no clue what brought this on. 

So, this is where i ask, WAS i too cheap, or is she just materialistic and psychotic?
<bot>: GF thought my 6-year anniv. gift was too cheap, she bought me something over our price  limit.
