<human>: *I wanted to do something nice for my boyfriend for Christmas and he's always wanted a puppy so I went out last night and made the stupid compulsive decision and got one. He loves it naturally because he's a dog lover but what I thought I was paying for it wasn't true. I thought i would have a two year payment of 133 a month to pay for the puppy and his supplies that were purchased from the pet store on credit with their new system bu that was lie. My boyfriend checked over the paper work after  and it was 32 payments for a grand total of 4500.00 instead of the 2000.00 I was under the impression I was paying. We have the option of paying the 2000.00 within 90 days without it doubling but that's all our money. Every last fucking cent, how could I be so stupid? The lady talked so fast and I thought I understood, we don't have that kind of money.We live in a run down apartment that takes the main bulk of our cash, I'm a college student, my boyfriend FINALLY broke even and could have started saving. I'm so worthless, so fucking stupid, I ruined everything and stressed out our lives more. We can't afford Christmas now or even my birthday next month, and before I get messages about returning the dog, its non-refundable. I hate myself so much, just wanted to do something nice and it blows up in our fucking faces, I get a fixed income from my college, I could have made the twenty four  133.00 payments and it would have been a gift but now we have to scrape by for my shitty fucking mistake. I just want to die.

Can you summarize the given text in a few sentences?
<bot>: Thought I was paying 2000.00, was tricked into 4500.00 unless I pay the first number in 90 days. I hate my life.
