How do I get my girlfriend to give me a break (It's long, but I need help really badly)?

I don't want to offend you, but it seems as if your girlfriend doesn't care about anyone other than herself! If you've really done all of those things that you've listed, then you seriously deserve so much better than her... I don't really think there's anything that you can do to make your girlfriend give you a break other than making the break permanent...
