<human>: I'm 18 and she's 17. We've been in a relationship for little over 2 years now. On Friday I suggested we should go and have lunch on Sunday, and she told me she was craving crab. She then told me it would cost $50+ for that dish and I reluctantly agreed.

Fast forward Saturday night, I really did not want to pay that much for $50 because I personally believed it was ridiculous. I thought she was being extremely inconsiderate because she wasn't understanding my perception on this. She said things like "Am I not worth going on an expensive date once in a while? The one time I ask you to eat an expensive lunch with me you shoot it down. Thanks for ruining my birthday week (her birthday is on the 15th of August). I apologised because I did not want to continue arguing with her. She told me to forget about the outing. 

On Sunday she tweeted about how she still wasn't forgiving me, and in retaliation I texted her that "I wasn't even at fault". We argued about some semi-related things and then as a serious suggestion I said, "Can we get a mediator like Wendy or someone" and straight after that I asked "What is birthday week anyway? Do you celebrate your birthday for seven days? I don't know what is." She flipped out and said "why the fuck would you want to bring other people into our fight" and I suggested it because quote: 

"I wanted to know if I was the only one that felt that way [about the price of the food and my reluctancy]. I did not realise you would be so offended by this. It's just like talking to Nathan [at good friend of hers that she would talk to, about relationship problems with me]." 

She then told me "do whatever the fuck you want, don't you dare expect me to talk to you for the next month".

Can you give me a shortened version of the text?
<bot>: She wanted to have crab for lunch, I did not, she got butthurt and we argued. She flipped out when I suggested a mediator and she isn't going to talk to me for a month.
