<human>: Can you condense the text into a few key points?

My girlfriend and I have been dating for 7 months, and some of our differences are beginning to wear on me/make me jealous. We are in college, and I, being an introvert, have very few close friends -- in fact, I really only have one, my roommate. She, on the other hand, is extremely popular, and is constantly being invited to elite parties by her many friends…many of these parties I am not invited to (not even by her -- they're "invite-only", and her best friend (19 M) who hates me for compromising her attention, is invited to these parties, smug because I am not). She is just one of those people that everyone loves, and I feel like I'm the opposite (I have always been shy and not very outgoing, although I do try to be). I don't feel like we're equals, I constantly feel inferior to her.

Another thing that separates us is money. She has the financial means (supplied by her parents) to drop $400 on a pair of shoes without thought, while I hesitate to spend more that $10 on one meal, or $20 on a shirt (my parents are far from wealthy and almost all of my money is earned myself, at my minimum wage work study job.) While it's not her fault she's rich, I can't help but feel jealous of her carefree lifestyle when I am constantly stressing out about the insane amount of debt I'll have upon graduating college. 

I wonder often if these differences will start to distance us -- to me, it feels like they already have. I guess I am seeking advice on dealing with jealousy, and inferiority, as I feel like I will never measure up to her. For a relationship to work, should both members be more equal, socially and/or financially?
