I need help about a situation with my girlfriend and I?

I'm 22 and my girlfriend is 20 and has no clue of what working and having to earn something is, she's been very blessed to be in a good family and get whatever she wants and such , like for instance , a brand new vehicle 2009 325I BMW , her parents paying for her to go to a $54,000 a year college(BU) and a $500 week allowance and I'm very happy that she get's all this , but lately I've been having a hard time, I used to work 50 hours a week and make $900 a week and got hurt with no insurance(I worked under the table) and lost my job over it and had a $12,900 medical bill and had to sell my vehicle to pay it that I worked hard for, a 2006 Infiniti G35 coupe and I have a rough time with my parents because they are complete , and now I work a 40 hour $350 a week job and have been walking to work 5 miles each way everyday for the past 2 weeks that I just started because finding good paying work right now is impossible , today I had the day off and I searched everywhere for a vehicle(no internet at my place and regular cell phone so I have no internet access and I walked probably 15-20 miles all day searching) and couldn't find anything for a good deal that was mechanically good (I only have $1500 to spend right now with keeping $600 to put it on the road) she would of taken me but she had school and my friends were too busy with work and 2 others with their kids, and she calls me up tonight and said "hey honey are you coming to see me tonight" I said "I'm exhausted baby and need some sleep ,I'll come see you tomorrow" she flips out and says "what the ****, why are you such an and loser" i said " that was really uncalled for and not right to say at all" then she said "Don't even bother seeing me tomorrow" so I said "you know what, I love you , goodnight" then i hung up , what should I do about this , That was really uncalled for and ****** up , I do nothing but nice to her and didn't yell back or say anything back even tho I could of , Anyone have any advice , I thought I should just wait for her to call me back and apologize? She really needs a wake up call and see how hard real life can be , she's stuck in a fantasy world , and It's killing me because It's the person who I love the most hurting me so it hurts a million times more coming from her!
